"Every time I tell her"? I think the proper thing to do, when you don't like someone's partner, is to just tell them once, giving your reasons, and then leave it alone and let them figure it out for themselves. Nagging them constantly is going to force them to choose between the two of you, which is not something you should ever do to a friend. That "If you're friends with him, you can't be friends with me" kind of stuff is bullcrap. You have a relationship with your friend. She has a relationship with her boyfriend. They are separate.
