Be careful, beating up a guy who tried to break you two up may actually break your relationship up, depending on the chick. There are a lot of chicks who find it seriously offensive when their boyfriend is so insecure and violent that he has to cause someone physical harm for something he obviously wasn't going to succeed with (according to the chick). So they'll take it as a personal insult, thinking that you thought your girl was that fickle (which chicks who are seriously into you and like that will take as a mortal insult about their character). Also, even if she's not that much into you, if the chick thinks he's a friend, and you beat that friend up, you WILL make him the underdog. Underdog + you look bad (violent and insecure) = she'll leave you for him, as "at least he isn't some violent, baboon without any trust for me".

I've seen these things happen too often, and heard about it too often as well. :-/
