I think my marriage is doomed. Any advice?

Ok, my hubby has never been a lover. He's been a fighter in wars and in his work and home life. I've been trapped in a nearly loveless relationship for years. We're coming up on year nine and last year I almost left him for someone else. Now I have no love at all. He made some threats to this other guy and we've been in court for 10 months for Theft by Extortion since my husband thought the guy should pay our debt off if he wanted to have me. Now we've had to file bankruptcy and the lawyer advised me not to work to qualify. My husband says he is too stressed out emotionally and gets cusses every time I mention our relationship. He says he shows that he loves me by busting his *** every day going to work. He says that while he was busting his , I was been swooned by another man and it isn't fair. Problem is I married him for security and not for love, but now I need more love. We've been fighting so much and now I just don't expect love from him. He keeps saying he is dying because he has holes in his legs (deterioration). He says he is beat up to hell and the last thing he wants is me giving him a guilt trip. As I've told myself already, my man is a paycheck and nothing more. If I expect more, I get burned. This is why I cheated on him in the first place. I wouldn't do it again, because he'd probably kill me. He is a marine and hangs out with Hells Angels. He has it in for this guy and his entire family as it is. It's all my fault. If I had cheated on a normal guy, I wouldn't have to fear as much. I'm not sure how to handle this violent husband I married. I'm thinking of never calling at work and just doing my thing. I'll be polite, but never ask for anything and never complain about anything. What do I do with that?
