I am the drinker and early this year my wife gave me an ultimatum to get sober, stay sober or get out.
It has only been about a year but I am doing what she wants and our relationship is stronger because of it and my desire to drink is gone.
I promised her I would do it and so far, with the help of SR I am becoming the man that she deserves. I know a year is not a long time and I don't know if an ultimatum is a wise thing but I do know that it is the push that I needed and for that I am thankful.
Perhaps SR could help him get to where you both want to be together.
