I hope you enjoy this story. I believe my spouse was engaging in a romantic relationship with his half-siblings due to their peculiar actions, but later learned that she had actually attacked him during their university days and has been blackmailing him. Him for years to keep it secret. I believe my 24F, husband, 24M, and his stepsister, 23F, are having an affair, my head is spinning and I don't know what to do. My husband's parents got divorced when he was 15 and his dad

remarried when he was 17. His stepmom has one daughter, let's call her Jess, who was 16 at the time of the marriage. They all lived together for about a year and a half before he left for college, which is where him and I met freshman year. Our sophomore year Jess began going to the same school as us. He introduced her to our friend group and she quickly became a part of it. They always seemed more like friends than siblings because obviously their parents didn't marry till they were older, but they'd sometimes refer to each other as bro and sis. Back then I sometimes got the vibe that she was flirting with him, but he never returned it and I just brushed it off as her personality and that I was being crazy BC no way that

would happen. Fast forward to now, we all still live in our hometown and see each other pretty often. Jess is single and hasn't had a boyfriend in several years, her and my husband are still very close. When we are all hanging out together, including their parents, if we're sitting on the couch she will sit right up against him, sometimes even put her head on his shoulder if he's showing her videos on his phone. I have always found it odd, but again have brushed it off. Of course they aren't actually related, but it would still be too taboo and weird, so I've never fully let myself

have the suspicions. However, over the last six months things have been getting weirder. Both my husband and I's birthdays are in April and only a week apart so over the last couple years we've kind of just combined them and celebrated both at the same time. We had friends and family over, and normally we also receive joint gifts, but this year Jess got my husband something specific to him, fairly expensive gaming headphones and a watch, but nothing for me, and she also got him a card and wrote a decent amount in it. I didn't get to read it when we were opening things and then later on I couldn't find it. When I asked my husband where it was, he brushed it off saying, oh, he must have accidentally thrown it out with its envelope, but the envelope was still with it.

everything else on the counter. They've been texting a lot more and she's also been talking to me less. Remember her and I have been friends for the last five years. Sometimes I'll see texts from her pop up on his phone screen and there will be emojis. This will be while he's holding it and he'll unlock it pretty fast so I've never really been able to see what they say. If I ask her to meet up or hang out with just me, she's always busy. But if it's her coming over our home to see the both of us she never says no. He also has been going to see her more often, which is kind of a complicated detail BC she still lives at home with her mom and his dad, so he just tells me he's going to hang out with his dad for a bit, but I have a feeling it's for her. Him and I have also been less

intimate lately. Neither of us have ever had super high sex drives, but we have always averaged at least twice a week, and now it's about two to three times a month. What's pushed me over the edge is when we all got together this past July 4th. We were at my Phil's house for a big cookout slash pool party. While in the pool she kept hanging on him from behind. Picture him giving her a piggyback ride in the water, splashing him, being overly playful, etc. I kept thinking in my head I was crazy because maybe after all these years they really do have a sibling-like dynamic and she's just messing around. But I also caught her staring at me when my husband and I were being close and she looked angry.

Now, cut to the worst of it all. We all were done in the pool and went inside to change. I was with my husband in his room and right in the middle of us changing she came in without knocking randomly asking if she could borrow my hairbrush. My husband didn't have any clothes on. I was horrified and said something like, OMG, you need to knock first. She seemed unfazed and lazily covered her eyes saying, oh, whatever, he's basically like my brother. My husband seemed kind of embarrassed, but also not as much as you'd expect. She left like it was nothing.

Since then she has barely spoken to me at all and I am absolutely spiraling at the thought of this. Am I being crazy? I haven't said anything to him yet about this because I'm so scared to be wrong and then I'm just accusing him of sleeping with his step-sister. I need others to tell me if they agree with what I've been seeing or not. Small update. Thank you to everyone who has responded. When I made this post I was hoping for validation of my worries but also scared of that at the same time. I'm trying to keep it together and act normal around him the best I can.

Tomorrow he's going over his dad's, so he says, so I plan to show up there and see what's going on. Update, hey everyone. Sorry that it's been so long since I made my original post about this. To say that our family has totally imploded since I last posted would be an understatement. So much has happened that I never expected or was prepared for so I apologize that I kind of ghosted all of you, but this has been really hard. Just an FYI, I'll be mentioning text messages a fair amount and it'll be paraphrasing. Leaving off from my last update, I did go to his dad's house that weekend that my husband told me he was going to see him. When I got there, only my husband's car was in the driveway.

I wasn't sure what to do, if I should try calling his dad, calling my husband or what. I decided to just go in because I didn't want to play games. I walk in and hear his and Jess' voices coming from the kitchen and it sounded like they were yelling. Even now I couldn't tell you what they were saying. I was so full of adrenaline as I approached them it was like I was watching them on mute or something and not actually hearing what was happening. He spotted me and looked like a deer in the headlights, and all I could muster up was to say what's going on.

I stared at them for a couple seconds and then my fight or flight kicked in, I'm very non-confrontational so my instinct was to turn around and run. He chased after me and pulled me into a guest room to talk. Again I asked what was going on, that he's been acting so weird and so has Jess, and point blank asked if he was cheating on me. He seemed shocked at the question but then out of nowhere started bawling his eyes out. I've never seen my husband cry before. He said that no he's not cheating but has something to tell me but couldn't do it there and

needed to leave slash for us to go back to our house. At first I protested and said no I needed to know right then and there but he still was having a breakdown begging me so I agreed. We left his car there and drove home together in mind, but I sat in silence the whole ride as he cried and was trying to collect himself. When we got home we sat in the living room and I once again asked him what the fuck was happening and my patience had run thin. Then out came his word vomit. He told me that in college, our junior slash Jess sophomore year, after him and a bunch of our friends had gone to a party, we were dating by this time but I wasn't there that night. I'd come home for the weekend to hang

with family that was in town, and he got really drunk. Our guy friends kind of ditched him to go hookup so Jess offered him to crash on her couch for the night. Our school had on campus apartments and she had a single BC she was an RA. He said he woke up at some point after that, with his pants down and her on top of him, having sex. He told me at the time he felt out of it and didn't really get what was happening and that's all he remembers was waking up and feeling it slash seeing her. He then woke up again a couple hours later and she was a son. in her own bed, so he left and went back to his own dorm. He never told anyone. It took him a long

time to even fully understand what had happened and he felt like he couldn't tell anybody because one. He felt ashamed and embarrassed too. He didn't think anyone would believe him three. He didn't want to be known as the guy that slept with his step-sister four. He was afraid of losing me and He was worried about his dad and if he found out that it could affect or ruin his new marriage and that his dad is so happy with his stepmom. He told me he basically just acted like nothing happened, even around Jess when we all hung out together. He said him and her never spoke about it or said anything until a couple years later, when him and I got engaged after graduation. She sent him a text essentially saying she loved him and thought about that night all the time

and that why did their parents have to meet and get married, they could be together otherwise, etc. Essentially she is obsessed with him. Shamefully, I will admit, when he first told me all of this I wasn't sure what to think or believe, until I saw their text messages. I questioned him saying if this was the case why are they always talking, why wouldn't he distance himself now that were married and out of school? He told me it started up again with her, about six months ago like I said on my original post,

when him and I told our families that we decided we wanted to try for a baby. He had a screenshot of the text she sent him the next day ranting about how he shouldn't do this. Marriages aren't permanent until a baby comes into the mix. There's still a chance for them to be honest with their family and for him to leave me, she still loves him after all this time, etc. He replied saying he loved me and wanted to start a family with me and that he didn't love her in that way, and he never wanted her to bring this up to him ever again. That's when her demeanor changed and she said if he didn't love her, why did he F.C.

her and what would their family think, essentially blackmailing him. I read through as many of their texts as I could handle and it was always her saying things like she was thinking about him, she wants to see him, she'd even send texts while we were all together telling him he looks good in that outfit. Sometimes he wouldn't reply and others he'd be trying to have a normal convo slash steer it in a different direction, and sometimes just telling her to stop it. The days he's told me he's going to hang out with his dad, it's her begging him to go over there so she can see him or she will tell her mom everything.

So he'd agreed to go but he swears nothing has ever happened, that one of their parents would be there a majority of the time and it would just be all of them on the patio or in the living room. That that day, he went there to tell her he was sick of it and couldn't do it anymore. She could tell people whatever she wants but he was done, and that's why they were yelling. I sat there taking it all in and honestly was speechless as I did not expect any of this. I asked him about our sudden lack of intimacy, essentially only during my fertile window since we're trying for a baby but never any other time, and he said all of this being brought up for

him mentally has made him shut down about sex. He was only doing it for me BC I want a baby. But it's taken him so long to realize slash come to terms with the fact that she assaulted him. and how this harassment. I cried. I felt betrayed by her and then a heavy, deep empathy for him. I just hugged him and cried and he cried too. I told him he really needs to tell his dad because we can no longer associate with her in any way,

and how can we manage that when she lives with him? At first he said no, he couldn't because he's worried they won't believe him and also doesn't want to ruin his dad's life because how could the marriage with his stepmom survive this? I told him I don't have an answer for that. He has to trust that his dad will believe him and I was also worried about her panicking after their argument and doing something crazy.

He agreed to tell his dad and said he wanted to do it alone. The following weekend he met up with Dad and told him everything, showed the text to him, etc. His dad believed him and like me was caught off guard and speechless. This led to him telling his wife and saying he was kicking Jess out, however his wife did not believe it. She claims my husband must have edited the text somehow, actual texts in the message app that you can scroll through, and it's Jess number attached to the contact. Jess freaked out, saying none of it was true and he was the one who'd been harassing her.

That's when my husband threatened to take it all to the police for an order of protection against her if she did not tell the truth, and she finally admitted to everything in an insane meltdown. His stepmom is horrified, his dad doesn't know if he can get past her not believing my husband and accusing him. We are currently in this weird limbo phase of the whole family on edge. Jess is still living there, his dad has demanded she leave and has given her two weeks instead of kicking her out on the spot in an attempt to try and salvage the situation with his wife. My husband and I are having lots of talks, trying to regroup. We've put trying for a baby on hold as he seeks therapy for this. He still is considering going to the police for the harassment.

My heart is broken for him and also trying to come to terms with the truth. That Jess who I've known for years would do something like this. I was prepared to uncover an affair but never this. I'm not sure if there will be any more updates after this, maybe if my husband decides to pursue legal action. I want to say thanks to everybody who pushed for me to dig into my suspicions otherwise this could have gone even further. I don't like to think of what could have happened.

Next story, wife got pregnant and I accused her of cheating and demanded a paternity test even though she never cheated. So she moved out and filed for divorce after the test proved I was the father. I met my wife through a mutual friend. We were friends for a year or so before we both became single and decided we were compatible enough to date. We were together two years before we got married. I do not know what got into me.

My wife is loyal, faithful, but I had been able to be. reading statistics about how many men are raising children that aren't their own and had absolutely no idea around the time she found out she was pregnant. We both wanted children, we weren't actively preventing it. About three months in, I couldn't take it anymore and told her I wanted a paternity test. She asked me if I was accusing her of cheating. I said yes. She asked me why, and I couldn't answer her. Neither of us has ever cheated or been cheated on. She said, She works very hard, long hours at her job, but has always let me know where she is slash who she will be with.

If she was going somewhere with friends, I was always welcomed. I do not know why I did this, and it's tearing me up. She told me she'd gladly give me my paternity test, but that she was moving back to her mothers until that time because she didn't know if she wanted to continue the marriage. She got an amniocentesis test at about 20 weeks. I'm the father, and when she told me, I was so very. happy. But she wasn't. She told me that she felt like she fell out of love with me the minute I asked her and that she had no desire to reconcile. Our daughter was born July 10th. My wife has

gone through a lawyer and has started through the motions of divorce and issues of custody. She has since gotten her own apartment. She said she wants to keep this as amicable as possible for the sake of our daughter. But I just want to be a family. She doesn't want support or alimony because she makes more than enough to cover herself and our daughter's needs and live a comfortable life. It's taken since February to even get her to soften her stance and even think about counseling. She said she loves me, but she isn't sure she can get over this. Now I'm trying to think of how to fix this, and I'm just such a broken mess. I want to prepare a list to talk about on Monday at counseling, but I just can't think of anything but apologizing and that hasn't made a difference

in the past months, I don't think it would now. Update 1, I got to sit down with my wife during my visit with my daughter while she was napping. She says that this was the straw that broke the camel's back. Here's why she went nuclear as a lot of people said. As much as this hurt, I needed to hear it. I had trouble trusting her our whole relationship, despite the fact she had never cheated on me or any exes. She's caught me snooping through her phone slash email slash work laptop before, and because she deals with privileged information, she says I open her up to liabilities with her clients.

No, I have never found anything incriminating. She has never hidden anything except work-related things because of confidentiality. Her bank accounts, credit card information, phone records were always open to me because she's caught me snooping before and she wanted to assuage my fears. I had recently installed Tinder on my phone and she had caught me on OKCupid six months ago. her best friends sent her my profile. So the things that this is me projecting, she got upset about the hypocriticalness of it all, while she had to be fully open to me,

but she says I never showed her the same courtesy and always bitched at her about my privacy. I had my phone passcode, would get upset if she did the same, and I'd get angry with her if she went into my computer slash email for any reason, even if it was bill related. She said what really made her not want to work on it was some of the following.

She felt no support for me at all before the test. She would come over every other day and talk to me, but I was cold to her and that she tried to work on it in the beginning. She said my aloofness made her not care, I refused to help her cover the copay for the amniocentesis. She said this was pettiness that made her feel this way, but she was going to get an amniocentes test anyway because she's paranoid about birth defects and her insurance didn't deem it medically necessary. I went on a few dates after she moved out and she found out. She considered it cheating because she had been attempting to work on our marriage at that point, and had even made counseling appointments that I refused to attend until she got the

paternity test. I didn't remember about this and didn't include it in my last post. She said she's willing to work on the marriage, but she said that it has to be as open both ways and she isn't willing to move back in with me right away. I have to give her the passcode to my phone and delete Tinder. I do not want to give her the passcode to my phone because I think I deserve my privacy. Her other condition is personal therapy as well as the couple's counseling. I don't want to do this either, because as many of you have pointed out that there's nothing wrong with wanting to be sure. Update 2, I realize now that I'm not exactly someone you want to sympathize with, and I'm sorry.

I do love Marissa and want to be a better husband and father. But I will not get that chance. In therapy, our therapist had us lay everything out on the table, and I admitted that I was an unfair hypocrite. She admitted that she's happier without me, despite being a single mother for all intents and purposes. We attempted to talk it through, with her laying out her terms to re-enter the marriage. I still I feel I did not cheat on her because she left me with no discussion of terms. She feels I cheated because we were still married and actively discussing her eventually rebuilding her trust in me and moving back home. We agreed to try another therapy session,

but Tuesday morning she canceled it and she filed for divorce. We had dinner that night. She told me she was sorry, but she didn't think it would work because her trust at this point was irrevocably broken. I told her it was okay. We sat down and talked about visitation until she leaves in January, when she will be moving to her home state with an opportunity that grants her more money and better benefits, including on-site daycare. She told me she harbors no hard feelings towards me, but she wishes it hadn't ended this way. I told her it didn't have to, but she disagreed and said it did. I told her I'd give her access to my phone and such, but the fact that I did that to her left a sour taste in her mouth about it, and she doesn't want a relationship

where it's considered normal to not share slash rifle through the other person's things for no reason, as she put it. We agreed on child support, and we will get it in writing. I make a comparable amount to what she will be making, so we agreed to split baby's expenses. Baby will be on her insurance. I gave her a check for the amount for the amino. Anything else we can think of? I know there's no chance of getting my wife back now, but how can I be a good dad to baby long distance? We talked about me eventually moving to be in proximity. She made sure to emphasize for Baby, that we will not be getting back together, but I'm locked into a contract until next December at least.
