Hi, dorothy,
I'm sorry you're dealing with this. It doesn't sound as if he has any interest in quitting drinking, and as bad as this is, it will only get worse. It sounds as if you've got (at most) a couple of hours a day of "amazing, loving, supporting, protecting" and the rest of the time is drunk, obnoxious, and abusive. Doesn't sound like much of a "deal" for you.
I know you love him, but this situation is eating away at you, and YOU are the only one who can stop it. What you see right now is the best he will EVER be, unless and until he works hard at recovery (which doesn't seem imminent). Is this what you want for the rest of your life?
I'd suggest you start going to Al-Anon and get your head clear so you can make some good choices for yourself and your future. And please be SURE you are practicing good birth control--everything becomes monumentally more complicated if you share children with an alcoholic.
