Back when I was feeling better, I interned at a domestic abuse center for a crisis line. This sounds like emotional abuse to me, which qualifies as domestic abuse. It doesn't always have to be physical.
I know that every person has their own timing to get out of a relationship like this. If you're not ready, you're not ready. I think you should try counseling if it's something that you can afford. I completely second what JB1 said:

I'm sorry your going through this. Its not right or fair to you. You don't deserve this. Please know that you did nothing wrong. Your husband has issues that has nothing to do with you.
There is a domestic abuse hotline if you just need to talk to someone privately about
what's going on. 1-800-799-SAFE. This is only something you should do if you know that your husband is not around. Having worked at a crisis line like this, I know that these people would be able to give you options for the situation and would not pressure you to leave if you're not ready.
Best of luck. We're all rooting for you.
