Why do you like him? Is he rich? Is he funny? What's the truth behind the infactuation? What are you going to do when he wants to go to a club? If you really like him for the right reason, tell him the truth. Don't wait "until the time is right". I dated a guy who lied abou this age. Had he told me the truth after a few dates, I would have shrugged it off. Many people fudge a little on their age at some point. However, he waited until months of dating to tell me the truth. I could never trust him again. This could happen to you.
