Wow. It's funny that you posted because I was thinking about you today and wondering how you were. I wish you tons and tons of amicable dust with the divorce.
I want you to know that his drinking is not your fault. The fact that he blames you is an indication of his level of denial. But regardless of what you do/did, he is fully to blame for his behavior. He is in control of his drinking and you are not to blame. If you want someone to go to al anon, I have been itching to go and haven't. Let me know if you want company. Big hugs!!
