So I recently got out a relationship with a guy that I have been best friends with for a year, we have had a really good friendship, and both liked each other, so decided to give it a shot. Everything was going fine. We were really doing good with each other, we never fought with each other, just had tiny arguments, we were just doing so good. Until I mentioned my prom, which is still a ways away. I guess it freaked him out, and he said he couldn't do it anymore.
He said the idea of a relationship was scaring him, and he didn't know how to handle it, said he felt trapped in, he said he was happy being with me, but happy being my friend too,
Now the hard part is we have to try to be friends again. Its very difficult because I care about him a lot, and I am crazy about this guy. And I'm so used to being able to kiss him, and have him hold me, that its so hard to go back to being friends.
So how do I deal with this!
Is there any way i can help him through it, or do i wait it out and still be there for him and still be his friend, I just don't know what to do with this, I have never been in this situation. I want to be his friend, But I know I want to be with him too. He has told me he misses our relationship, but doesn't want a girlfriend, what do I do? How do I be his friend when I desperatly want to be with him!

It's up to him to decide whether he wants to come back to you. You can't force him to come back, but you can accept his decision and respect his wishes.

If you can't handle a simple friendship with him, then maybe it's better to block him out for a while, at least until you're feelings for him have gone away before you try to rekindle your friendship. Otherwise, you're just going to drag out the pain and suffering.

Oh I know that I don't want to force him to do anything at all, I'm just curious what works when I'm trying to put his mind at ease.
Regardless of anything, I still want him there as my friend

Then there is your answer. Being just friends with someone you have feelings for is never easy. Maybe you could start a new kind of friendship where you are still friends, sure, but you also have plenty of time apart and with other people more.
