If he hasn't asked, then don't say anything. If he has asked, please go w/what Matt suggested. Lectures don't work on them and you may not realize it or not, but what you posted sounds like you want to guilt him for what he's doing. The best way to handle people who act like this is to ignore the behavior, be short and sweet w/responses.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
