You don't need to lecture him and tell him everything he did wrong. He knows. IMO, I would say nothing. That hurts him more. He will eventually get it that he has a problem and needs to deal with it. (Hopefully, but not likely)
Hit an alanon meeting, keep posting, and reading all the stickies at the top. You need to educate yourself about addiction. This is a progressive disease and it will only get worse.
