My boyfriend has a group of friends and one of them I can't stand. I'm gonna call him Kyle because honestly fuck Kyle's (jk, take no offense good Kyle's). Kyle has a girlfriend who I've met but we aren't friends. She seems nice but Kyle talks so much shit on her. Its not even things about her relationship or that she's crazy or anything. He's called her a fat whore, a clingy cunt. Talks about scars she has on her belly. He also let's another friend in their group talk shit about her too. I asked my boyfriend why he doesn't say anything and he says its none of his business and he doesn't do other people's relationship drama. And Kyle acts so sweet to her face so I don't even think she knows how badly he talks about her. My boyfriend won't say anything to Kyle because he doesn't do drama and Kyle isn't really his close friend. Kyle wasn't originally in his friends group. He just started hanging out with them because another one of his friends introduced him and now he's just there. I just think its sad and I want to say something to her but my boyfriend says to just stay out of it. It will do more harm then good and to just ignore him when he's being an ass. I just don't think anyone deserves to have their partner talk about them like that.
