I think during the times we are so full of anger, we think there will be a haha moment when it all falls apart for them. As we become more healthy, it's natural to let go of some of that anger because if you don't you are simply hurting yourself.
It is sad when someone lets their life fall apart like that. Sad for him, for his children, for you.
I am glad you have detatched and are no longer in danger, same for your children. You turned him over to God, only he can make the right choices.
My XAH came into the house the other day ranting and raving about things that happened when I was not even present that day. It was crazy nuts and I calmly made him leave. The thing is, he is only hurting himself and digging his hole even deeper.
Fact is, alcoholism is progressive and as it progresses it makes bigger and bigger negative effects to the addicts life. It's very sad to sit by and watch that happen. I am not sorry he has consequences, just sorry for all that has happened to you and your kids.
Big Hugs.
