Hi Satellites,
What you can do is keep reading on SR and begin going to Al Anon. You will learn that his problem is entirely his, and slowly start to accept it. I really think hearing the stories of women who married alcoholics might help you save yourself from a similar fate. You were healthy enough to find SR on your own; that's your survival instinct at work.
I am a forty year old mother of two. Luckily, I did not marry the alcoholic I was involved with, or have children with him. Still, my relationship with him was the most painful thing I have ever experienced. I live with immense regret now. I will never get back the time I spent with him, and rebuilding my shattered self esteem from his emotional abuse has been so difficult.
You don't have to make any decisions right now, but please commit to educating yourself about this devastating and horrible disease.
HUGS
