I think you did the right thing..."he has personal problems". Pretty much explains it all without detail. No apology. I've had people stop by our home and AH is still in bed at 1pm from the bender the night before and I just say "he's recovering" they all know what it means. Or a family member calls me about some stupid texts he sent the night before. I just say "he was drinking". I refuse to cover or make excuses. It is what it is. He can deal with the questions later. It's not our job to pretend all is well when it's not. I'm done with that.
