There is NO excuse for cruelty, and he is CRUEL. I don't know what he's trying to accomplish here, but he's certainly doing a good job of screwing up.
You don't hurt people just for the sake of hurting them, and that seems to be what he's doing. I dont' know what his "plan" is. Is he trying to get you to leave him so HE doesn't have to be the bad guy and leave?
Why would he say things like this to you? And why do you put up with it?
I would DEFINITELY seek counseling -- and if he won't go, I would go anyway. And if the counselor advises you to seek an attorney's advise I would certainly listen. God bless and please take care. Hugs, Lee
