I'm sure every single story here is complex just like mine but I'm going to try to be brief. My wife and I have been married for about 2 and a half years now. Before we got married I introduced my wife to my cuckold fetish. While there are different levels to cucking I am somewhat masochistic, primarily emotionally. We have had several experiences that we both left feeling fulfilled and always communicate openly and honestly. I have encouraged her since the get go pretty much to enjoy this in any shape or corn she chooses, even stating out would be hot if she fell in love or even did things behind my back. I think there is at least one guy she had more than just sexual feelings for but nothing was acted on in that sense. As far as basically encouraging her to cheat, she several times over the years tried to indulge just role playing that scenario but in the end she always said she just didn't feel comfortable doing that and just could not actually do it. So fast forward to the past month. She is in graduate school and at a party she got drunk and fucked a classmate. She felt super bad about it because he has a gf. But at the same time she kept texting him and decided to see him a few more times including her spending the night at his apartment(which is gf lives with him but she was gone). They now have been texting every day all day. This has led to a lot of different things. I've tried not to be judgemental at all but I've also expressed that this could end up hurting some people. She agrees but doesn't want to stop. I made it clear that I feel she should. But at the same time because of all my desires I've played along. This is A) already longer than I intended and B) makes it clear we are both making bad decisions. I'm kind of at a loss of what to do. I feel like if she can make this decision what's to keep her from leaving me and causing pain for our children as well. She's also obviously already developed an emotional attachment because she stated last night that she does believe she is poly. Now we are both quite sure that this guy is not anything like that. So I even stated again last night that the only way this can end is in pain. She basically said she's ok with that and feels like she can't stop. I am more than open to being poly but I'm worried about her and us in this particular situation. I have a feeling I know what advice I'm going to get. But I'm struggling how to deal with this and know that I need to before it gets worse.
