So sorry for what brings you here.
I'm the "A" in my marriage. Drank for over 30 years before getting married. My wife did not know the extent of my drinking. I thought marriage would change how I drank. Lessen it, I hoped. It only got worse. Nine months into our marriage, after a night of totally out of control drinking, I quit.
I told myself my wife didn't deserve a drunk for a husband. But I don't think that's what kept me sober these four + years. I didn't deserve to be a drunk and my recovery had to be about me and my desire to get sober.
Same with your husband. He will have to want it.
