Wow, our situations are very very similar, aren't they?
Considering your H's past, I would recommend "Make Up, Don't Break Up". It will help you understand why he acts certain ways. While I think DB and DR helps you in the current situation, that book helped me maintain my patience.
Why don't you tell me a little bit about how you were in your situation? Like, for me, I always bit my tongue, never stood up to H. Were you a nag? Honestly ask yourself where you played a role in the unhappiness of your marriage. Did you always let your H walk all over you? What role did you play? Identifying this will help you do 180s.
It really seems that you are doing well GAL.
This is going to be hard. When you cry, let yourself. Allow yourself time to grieve when you need to.
But...embrace your new body, 20 lbs lighter!! (I DID!)
