Since you have asked, here is what I think.

To put it mildly your husband appears to have some issues, and aside from everything else you wrote, him injuring himself is reason enough for me to think that. I strongly suggest you suggest marital counseling to him and if he refuses to go, go yourself because something isn't right here. Actually, I think he needs to see a counselor for himself, but he likely would refuse, so I suggest you try the marital counselor first.
