Is your H going to AA or has he just "quit" cold? As you know the pain and issues that literally "drive a person to drink" are still present when they stop drinking, except that now there's no anesthesia. You cannot be his main support in his sobriety, but I think you know it. AA is not for everyone, and there are people who get sober without it. But true sobriety required facing the pain and dealing with it in some way besides alcohol. That is hard to do on your own.
I know that when my bf stopped drinking, our life together improved tremendously, but he didn't get into AA until a couple of years later. At first I saw even more change, but lately he's been skipping meetings. It's a long, hard, haul, and frankly, no one can say what are your long term chances for success.
That's why they say "one day at a time." I do have lots of hope and good wishes for you.
