Hope- I don't even know what to say, except that i feel your pain. I know there is nothing that can be said that would comfort you right now. What your H did is an awful thing, but it clearly indicates that he has deep-rooted issues that have nothing to do with you.
Please see a lawyer. I know you have consulted one in the past, but given this new information, I think you should know exactly what you are entitled to, and if this new development affects anything at all. Yes, having 2 lawyers battle it out will be more expensive. But, if that is what has to happen in order for you to protect yourself, then that is what has to happen. You need to start putting yourself first and stop worrying about him. He did this...he now needs to deal with the consequences of his behavior.
The things he said to you were probably out of anger and shame...don't listen to them. If he hated you, he would have been a lot worse to you. Not that that is any consolation.
You have been everything a wife should be...believe that. You did not deserve this. Stand up for yourself. Hold your ground.
