One of my close friends is sleeping with someone who's in a relationship with someone else. I know she's been through a lot with her husband leaving her but she just doesn't listen when I tell her she's selling herself out. I've found myself lately just not even wanting to be her friend, because of the choices she's made. I just feel judgemental, but I'm also disgusted by her lately. What would you do. I also know the guys girlfriend she's a bitch but it doesn't mean she deserves it.
