You sound like you have a very good head on your shoulders. I'm not so sure asking him to leave or your own leaving would be enough to make him stop drinking. That bottom is different for every alcoholic. Guess what I mean to say is, if you need to exit your relationship with him in order to keep your sanity and make a life for yourself and your children, then so be it. Your happiness and quality of life are worth something. You shouldn't have to sacrifice them for someone who is more concerned with drinking and living in a alcoholic haze.
