First of all I facebooked my crush and told him I liked him and well.. lets just say he wanted to be just friends well its so awkward being around him now we have not talked since and its really kinda hard because I was fine with being just friends but he didn't have to kick me out of his life completely I kind of regret telling him that I liked him now because now I have lost my best guy friend is there anything I can do to fix things?

It's only awkward if you make it awkward. You should just approach him casually like you have before and just say "hey what's up" and make conversation or whatever. It's normal for him to feel a little odd since he doesn't like you back and it can be difficult being the object of someone's affections, but if he's mature and truly is a good friend he'll be able to overlook things and go back to how your friendship used to be. Just try talking to him like normal and hopefully he responds. If not then you can just tell him that you wan't to forget about what you confessed, etc. and hope your friendship can continue. Best of luck.

Sounds like to me, that you need to be able to accept that he doesn't feel the same, move on, and if able, be friends with him, and nothing more. As far as him drifting away, you probably had a hand in that too, because you didn't know what to say or how to act once it was out in the open. You've gotta detach from the fact you told him, and try to bring it back to the way it was before. The feelings were already there, nothing has changed. Just do what you were doing already. You dealt with the feelings before you told him.
