Hes never on aim, how do i tell him i love him?

Okay so I went on a trip to hershey park for my 8th grade class trip. And I had the best night ever with one of my best friends. But it all started when we were holding hands on the buss ride. Then, comming back I was daresd to kiss him and I did, then...

we jsut continued and had so much fun with other, we laughed, kissed, makde out and I had the night of my life. But I moved, and I can't stop thinking about him, the only way I can talk to him is through aim. And he's never on!
I want to tell him I'm in love with him.
How do I tell him?
Why can't I stop thinking about him!?

First before you do do that you might wanna find out what all he is doing before you tell him that and be prepared for the worst because when you left he didn't have a girlfriend doesn't mean that now he doesn't and another thing also your really young your feelings are open for any guy (don't take it the wrong way) you need to analyze the situation and figure is the happiness gonna be greater then the pain cause with your age and the distance and the situation there is gonna be a lot of pain.
