ConfusionCraze: I understand what you're getting at spiritual_emergency but apparently Igave you the wrong impression. We didn't go to bars and I don't drink or use pot so no that wouldn't be an issue. He's been smoking pot for over a decade. He wasn't really into the gambling aspect of the casino that was more me. He didn't even have anything to drink that night..so the first sexual impulses weren't alcohol/pot induced. Mus've been just the hypomania starting like you said before.
Thanks for clarifying, ConfusionCraze. Meantime, I came across this link earlier today. If he does come back into your life and you want to resume a relationship with him, there might be some good tips there for you:
