Is it normal: my boyfriend enjoys fighting
Hello. Is it normal that my bf enjoys brutal fights with his friends? He's very kind, my parents love him, he always takes care of me, he's interesting, we always spend good time together and he's never angry, mad or stressed, he's not drinking/smoking, however, his desire to fight distracts me. He's been into roman-greek wrestling and kickboxing since he was a child. His friends are also good guys, kind, helpful and interesting, but they also are very deep into different fighting styles: wrestling, boxing, kickboxing, sambo etc. We've talked about this a few times and he told me that it's their "game", it's how he and his friends are having fun. This is NOT fun in my eyes, since I saw a few of those fights, this more reminds war: no rules, savage beating, blood, injuries etc. He also tends to pick more stronger opponents, more stronger than he is (he thinks that picking on weaker people is immoral and he also has a tendency to protect weaker people). Quite often when we cuddle I can feel that his body extremely hurts, but he tries to hide it from me. Also, it scares me to know with what kind of brutality he beats his opponent, he's in total rage and out of control when he fights. Once some thugs began to pick on me on a street and he went into absolute frenzy, sending them in near-death state right into hospital, while police took him away. However, he never raised his hand or voice at me and I doubt he ever will. And again, he's extremely kind and nice in real life to everyone.
Is this normal? I'm afraid about his health: he already has problems with his back and right elbow. Anything I can do to stop his will to fight?
