My wife has a group of 5 male friends she grew up with and about 5 years into our relationship she slept with one of them.

At the time I felt so bad, mostly because I knew they all knew about it.

I told her that I didn’t want her being friends with them anymore but she didn’t agree and continued to be friends and eventually the one she slept with fell away from the group but anytime I hear the name of any of them I still get anxious and hurt feelings which take me back to that time.

It was about 15 years ago now and I can go months without thinking about it and then the second she mentions one of them I get triggered and the feeling can last days weeks months and I keep bottling it up because when I have tried to talk about it she just says they are her friends and it was just sex, but friends wouldn’t let the sex happen right as they all know what was happening that one night when she took him to the bedroom while hanging with them.

Am I wrong to expect she should have cut ties with that group of guys?
