Is AUTHOR wrong in the post ? POST : Am I the asshole for telling my girlfriend that I dont want her going to her girlfriends house because her friends boyfriend is abusive towards her friend? 

My girlfriends bestfriend is dating a man that is, allegedly, taking steroids and very emotionally unstable.. She tells me all the time how this man is abusive towards her, emotional and physically, and very controlling. He also has a drinking problem which, probably, makes things all the worse. I feel very bad for her and have told my gf to tell her friend she needs to leave this man immediately and that's all we both can do for her. I've told my girlfriend that I don't feel comfortable her being there, just the two of them, with him. I told her that I dont want her being there with him and I dont trust him. I also told her that I would be okay if she goes out in public, to bars or restaurants, with other people around just for the safety of both of them in case he shows up. He has apparently followed her friend around to make sure she is not doing anything behind his back? She thinks I'm being unreasonable and he would never hurt my GF. I dont trust this man around my girlfriend, who knows what he is capable of. 

Am I the asshole for telling her this and not believing my gf can handle herself?
