My XAH never got sober, and most likely never will. He still believes he doesn't have a problem and that everyone else in the world is out to get him. He is a perpetual victim, hungry for recognition, eager to take on a new enabler, and skillful at exploiting the weaknesses of those around him to his benefit.
I left. I got custody and a divorce. I do not allow him to see our child as he is mentally unwell.
I have no regrets.
