From reading all of this... the absolute best thing you can do is just pony up, and walk right up to him and start a conversation. If he feels you like he does, than that akward phase will smooth over pretty quickly. In the end would you rather let him go forever not knowing what might have been, or would you rather walk away knowing instead of thinking? Trust me, regret is a to live with it. So take our advice and just start of the conversation, maybe start with "Hey, I saw you go to that club, do you like clubbing" Or a classic is, "hey I just got a new cell, do you want my number?" In the end something is better than nothing.
