So I read a good part of your sitch and it seems alot like mine was. You seem to be on the right track though. As everyday goes by you will get stronger. My H loved to text me all sorts of stuff to try to make me feel guilty. When i wouldn't respond he would get uglier. I finally locked all my phjones in my room and walked away. He called 48 times that day.
When you stop responding to there immature crap you stop giving them a reason to place blame on you. Right now he can justify his actions because of your re-actions. Don't give him any. Eventually they have to start looking at themselves and what it is they are doing because you are not helping them justify the A and leaving anymore. It's hard at first, but there is strength in all of us that we usually don't use. Find it! You can do it!!!!
