Do what you need to do for you and your children. Go to Alanon. Leave the H in treatment for as long as possible. Leave his treatment to him. Focus on your own recovery. When he gets out watch his actions. Is he responsible; going to meetings, giving up "using friends", not going to "using" places, getting a job ? One thing that helped me was the book Codependent No More. I saw I was as addicted to him as he was to booze.
