I've been in the same kind of relationship you are in now. If you'd like to keep your sanity, your life, and everything else you value leave the jerk. Trust me on this one. He will only try to bring you down further and further. He will do everything to make you feel terrible and depend on him.

You need to escape this hell that you are in. I wouldn't call it a marriage, I would call it hell, imprisonment, etc.

I'm here if you need me.
