well if he does all of these things the simple answer is "leave him" but i understand thats much easier said than done and these situations are complicated. but coming from one of those typical dysfunctional families with the cheating and abusive father, and going through 2 divorces (as the child of course) i can tell you i would be WAY more screwed up if my parents had stayed together. Im pretty glad they split up because I don't think I could have been around all that negativity for another 10 years until I moved out.
