My dad is the alcoholic. Back in my teens, my mom had had enough and kicked him out of the house (after attending Al-Anon for a while). He finally got the message and agreed to treatment. He was committed and successful in maintaining sobriety, but my mom had drawn a firm boundary. He remained out of the house for almost 3 years before they decided to get back together. They are still together to this day and he has over 27 years of continuous sobriety and they have over 50 years of marriage.
