I am so sorry for your pain, I can assure you that if he does not get help alcohol will always come first in his life, you will always be waiting and wanting.
Maybe he will get it together someday, it's very hard to watch someone you love destroy themself. You are doing the right thing, you cannot fix him, you need to work on your own recovery, heal your own heart.
Please come back often and let us know how you are doing.
Peace be with you.
Bill
