There is no way for anyone else to know or to judge another person, or another relationship. But Anon, if you came here today, you clearly need something. Maybe you should begin to focus on you and how you feel, and what you want in your life, rather than him and his situation and his alcoholism, and what he will or won't do, or may or may not feel, now or in the future.
Al Anon is a wonderful place; you can even check out a meeting on line. You can just listen (well, read actually). You don't have to participate at all. And there is a wonderful book of meditations Courage to Change. You don't need anyone but yourself to be happy.
While he's clearing his head, take some time just for you, clear yours. If you are meant to be together, you will be. Nothing else for you to do, but take care of yourself.
Just 2 cents from someone who has been there.
