Confused

I'm in love with a boy, who knows it, and exploits it. he will act like he likes me one night, and I will get my hopes up, and then it never goes anywhere from that, and he flirts with other people around me. part of me thinks he is selfish and just using me when he feels like some attention, but I want to think he likes me back but he's just indecisive. Am I being really naive?
I can't take getting my hopes up then having them crushed again. It hurts. I love him with my whole being, and I don't know why. I didn't want to fall in love with him, we were best friends and I wanted it to stay that way. It kind of just.. happened..
I don't really know what to do.
If I don't pay attention to him, he tries to get it, but if I text him or something he snobs me..

Typical shitty teenager. excuse the language. he's playing hard to get, taking advantage of knowing you love him, and still on the other hand probably likes you back. tell him to stop playing with your poor old head, otherwise you won't even bother anymore. he's just playing games with you, probably because he thinks you'll always be there.

Bangbang is right.... he is just seeing how much he can push you around... and believe me it hurts when he picks you up and then just drops you... so if he keeps playing don't talk to him for alittle while... make him talk to you first... and all that... and another thing i like to say boys are cheats and lyers.. and men are boys in big bodys.... so they never fully mature... i'm 15 and i have people at my town swear that my brain was taken by aliens and replaced with a higher brain... because of the small fact i look at everything and i have common sense...

Bangbang...this is totally off subject, not to be rude but i finally remembered where your icon came from...that one movie...the french one...can't remember the name....

This guy sounds like a total jerk, not worth the love that you give him. I know that doesn't make it possibly to stop just like that, but you cannot be his doormat, where he runs when he's lonely. You should get past him, he doesn't deserve you, and he maybe deserves a little heartache of his own. Trust me, I've been there...it's the best way. Just walk away from it.
