One of my bridesmaids has a very abusive boyfriend who she keeps going back to, which my fiance and I are less pleased about. She has a very co-dependant relationship, and goes back and forth between complaining about how horrible he is, and then to being defensive if I complain about him. I told her that he is not welcome at our wedding for a variety of reasons, and she flipped out saying that I am not taking into consideation that they are in a "serious relationship". Am I completely out of line for saying that someone who has literally broken my friend's bones is not welcome at our wedding?
