What now, though? Just GAL, live with the silence in hopes he starts to miss me and wakes up?
Yes, I'm afraid so. Until HE decides to do something about his drinking problem, there's nothing you can. As pro-affair-busting as I am, a drug or alcohol problem has to be solved first. The order is:
1. Fix the drug or alcohol problem. 2. Bust the affair. (which, really, is just another addiction) 3. Work on the marriage.
