A dry drunk is somebody who is sober, but hasn't delt with their past or current resentments and issues. He needs a sponsor to work the steps. That is the key in working through the issues to find healing and happiness. Resentments will eat away any joy if not delt with. This is refered to as untreated alcoholism. Unfortunately, nothing will change unless he's willing to make the changes needed. He knows no other way than living in a world of self centeredness and discontent. Until he steps out of that world, he has no other comparisons. He can find contentment if he puts some effort into it. I wish you and your husband the best. I hope he will listen to your suggestions. He needs to get a sponsor and work the 12 steps as soon as possible.
