Should I stay or go????

OK so here's the deal, I was married for 12years and then got divorced, met my boyfriend just as things were going bad in my marriage, and I've been with him every since, (we did split for about 6 weeks and got back together) I then moved in with him. Since then we have had HUGE fights including physical ones. I have found naked pic's of other women that he has had with (supposedly before we were together or the time we were split). Also anytime he get's upset with me he leaves and wont tell me where he is going, says it dosen't matter and when he comes home he is usually wasted. I just don't know if I should cut my loses now or cont to try to make this work?? I really do love him, I'm just tired of having to try to prove my love to him?
