It is a very difficult question to answer.
I was lucky in that I did not land myself up in an abusive relationship. However, if I was in the type of relationship that you have just described I don't think I would of stayed. I think you are currently at risk and should not be abused (only verbally for now)in this way.
Yes, he is a survivor but he is becoming an abuser. You sound very supportive but unless he takes a step towards recovery he will never heal.
I know it is not easy to hear this but get out while you can.
