One of my bridesmaids is in a relationship with a dirt bag. We have told her this, she knows this, but she stays with him because it is comfortable for her. Now, I'm talking dirt bag- he is emotionally abusive (he calls her a c*nt and other wonderful names), he is into gambling/drugs, he is jealous and causes a scene whenever we are with her. We have tried to get her away from this guy, but it is her decision. What I want to know is do I have to invite him? I know etiquette says that because she is in a relationship that I'm SUPPOSED to invite him, but I don't want to. I'm afraid he is going to ruin the wedding day for my FI and I and for my bridesmaid. Help!
