What will happen between this guy and me? What can I do to stay connected?? Please, important!!?

I'll be 16 next week, and he'll be 16 in 2 months. I liked him from the moment I saw him from across the room in 4th grade, and sat next to him for a whole month in 5th. We separated in middle school, and only talked a bare bit in 8th grade online. This year, we finally meet again. He tells me he wants to see me again, so we audition for a musical in a company we've attended a few years back, and by the last show gives me a hug and says "thank you so much" (for the support I always gave him, I guess, because he's been my influence to musical theater ever since). On he sent me a message on facebook, gave me a lucky kiss back, and asked to hang out, but then stopped talking to me and deleted me from his friends list when he got a new girlfriend 2 days after the last one. I told him after the show then that he's one of the most amazing people in the world, and he said "i'm one of them, one of 2 ;)" and I'm sure he meant me. He asked if the hangout was secluded when i told him...

...when I told him that I had a hangout place in mind (it's not what you think, it was just to talk alone). He's extremely popular in the theater and alot of girls want him to notice them.
I'm not single anymore, then I was, but why didn't he ask me out then?
What more could I expect from him?
This not-talking had happened in the past, so I know he doesn't mean it, but what is it? Did he like me for a long time but just didn't want us to be revealed and isn't sure himself what he wants? He's also athletic and a very good student. We're sophomores now.

It is apparent and clear that you still like this guy as more than just a friend. However, I suspect this guy does not see you in this same vein. Every thing you have mentioned suggest a guy who likes you as a platonic friend , maybe wants to be a best friend or buddy but not a boyfriend. But it is possible to know for sure; simply set a time and place for you guys to have an open, honest , complete conversation about your relationship and the direction in which it should proceed. While you indicate that you have a guy and he has a gal, I think this talk will allow you guys to examine what you guys feel for each other and if a romance is in the cards. Plus he is the only one who can answer all of the questions you asked here to your satisfaction. I hope it works out the way you both want it to.

OK! I know EXACTLY how this is. It's been going on with me and this guy for about a year now. I finally decided yesterday that enough was enough and that he's not even worth keeping as a friend.

Your 'friend' isn't worth keeping around either. Think about it--you've tried to be his friend and he kept leading you on.

The only way to get over him is to stop talking to him. But, you have to WANT to do it for yourself.

Good luck!
