My drinking was the largest and most obvious problem in our young marriage. Getting sober was necessary, for both myself as an individual and for the marriage as a team. His suffering certainly was a big reason for me quitting at the time I chose to quit. Our future was in jeopardy, easily.
That aside, getting sober removed that big problem and now I can see all the other problems.
The question remains as to whether this marriage is worth saving, and it has a whole lot to do with how he chooses to respond to me as a sober person. So far, it ain't great.
He isn't keen on some of the changes that have taken place in me and how I've chosen to be as a person. Now, I am staying sober primarily for ME. He just gets the side benefits.
