Code,
How long has your husband been abstinent? Is he following any kind of program? Do you really want to end the marriage?
I am the alcoholic in my relationship. It has been 3 years for me now. I am still married but marriage recovery is slow. Sometimes it is 2 steps forward 1 back. But, we try. You need to figure out what you really want. Do you want to take one more chance with your husband or do you want a fresh start?
