I remember my H acting like I was going to hurt him too. He wouldn't even come to the house...was afraid to be alone with me. I have no idea why he felt that way as neither one of us has ever gotten physical or even come close. I thought it was weird too.
One time shortly after sep, my H came over and had on new Oakley's. I knew he couldn't afford them and even said something about them. His response? Credit cards are great. Idiot. It is like they have no rational thinking.
I hope getting your half of the money will be painless. Your H just sounds like a dreamer...never satisfied, always grasping for that next thing that will finally make him "happy". He is going to have to work that out on his own.
