One thing I will say is that my AH was like yours, generally nice, made a good living, good dad to the kids, seemed nice to everyone we knew, until one day he wasn't. He was able to be a heavy drinker and mildly depressed person but functional until he was 39 and then he totally lost it. He has been an out of control crazy alcoholic for the past two years. So, your situation may very well progress. I NEVER thought this would get this bad.
