Input: Hey everyone. I’ve been work friends with a girl for two years, we don’t hang out outside of work much but we text/snapchat a lot and used to see each other at work until I transferred stores. I’ve also only met her fiancé a few times so we are not close. 

She recently told me that she’s been “talking” to a guy we used to work with. She and her fiancé have a child together and have been together for going on 10 years - it’s been clear that they don’t have a happy relationship but refuse to communicate about it. I’ve tried to be hands off in the situation because it’s none of my business, but then she started telling me that they’ve been hanging out and made out a few times when they were drunk. I told her that I’m not going to tell any of our friends or her fiancé about it but I cannot support her actions and want no part in knowing the details. 

She got upset because she thought I was being judgmental and tried to justify it by saying that she thinks he’s cheated on her in the past, which she’s never said anything about until now. She said she wasn’t asking for my approval but she just wanted to “tell me what’s going on in her life.” I said that she and her fiancé need to communicate better and figure out of they actually want to be in a relationship - she really didn’t appreciate me saying this. 

I generally really like her and am supportive of the decisions she makes but I just can’t support her cheating on her fiancé. Apparently this makes me a bad friend. We haven’t talked much over the past few weeks and I miss her friendship. AITA for essentially telling her that I don’t want to be involved with her while she’s cheating in her relationship?
