He asked about divorce

The other day, I came home early from work and he wanted me to help him with fixing his truck. I hate doing this because he is always horrible to me because I apparently don't help him the "right" way. So anyway, I was trying to help him and of course he got pissed and started calling me stupid and stuff, then he stopped and asked me if I wanted a divorce, and I told him yes. He then told me that he had the opportunity to cheat on me, but he didn't and that if he had, I would have deserved it because I had put us in debt. He then said that if I filed for divorce I would have to agree to pay him all the money he paid toward the debt, and money that he wasn't able to save in his retirement fund during the last year. I told him that the lawyer could decide that and he went irrate and said there would be no lawyers that I would have to agree to his terms no matter what. I don't think so. There will be a lawyer, or he would still try to control me through having me pay him for stuff that I should absolutely not pay for.
Later that evening, he went into his "We need to be Christians and work together as a team." speech. He thinks that if he gets rid of his porn addiction it will solve everything. In his mind, that is the problem with the whole marriage. He doesn't think that putting me down and grabbing my arm and putting bruises on it is the problem. (He did that right after yelling at me about the divorce thing). In his mind, he doesn't even think that all that stuff is wrong. He then told me he is going to try to change, but then he had a few temper tantrums yesterday and got pissed at me for stuff that shouldn't have been an issue and he acted like it was the end of the world. Then he tells me that I am not a "helpmate" because I am not being submissive enough to him and I have to stop my defiance now or he will "punch me in the face". Is he crazy, or am I? Insane!!!
