Welcome Confused.
I honestly believe that from all I have heard here in SR land, the best thing you can do, for him, is to take care of yourself. to go to meetings, and to let go of control of him. The things you learn, your toolkit, will give you what you need to survive, whether he gets into real recovery or not. There is nothing you can do to fix him, but there is a lot you can learn about addiction, and about codependency, which can make your life a living he!! while you may think you are helping.
meetings, reading the stickies here. and a book Codependent No More, by Melody Beatty, is amazing. Its about how to live your life, and not let anyone who is addicted/alcoholic ruin yours. You will need to know this stuff. Whether things work out or not.
If you keep your eyes only on him, it could happen that you will be whipped about like on a roller coaster, with no time to catch your breath. focus on you and taking care that you get the kind of life YOU want to be living.
big hugs, its rough.
