I was in the same boat.
I got sober and the hot mess that was my marriage/spouse began to appear. I was told to DISENGAGE from the drama and worry about my side of the street. And I did: meetings, steps, service work.
I did not know whether my marriage was going to last or not. When the time came (I was about 6 months sober), we went to marriage and individual counseling. We came to a mutual decision that we would find out if there was a foundation upon which to rebuild our relationship. We found that there was and we went to work. It takes work. A lot of work. BOTH people working.
His drinking became a hinderance to our marriage and although it was never said out loud, it was clear that he had to choose booze or his marriage. They could not coexist. The first day of the rest of our lives was when my groom picked up a white chip on December 31, 2010, 18 months after I came into AA. We have not looked back...except to make funny jokes about how the other used to be a drunken ass. lol
Good juju to you. :-)
