Why are guys two faced?

LoveisStupid
Okay, well every time I've ever liked a guy, he's always acted interested in me or at least pretended to care about me. Turns out they've been going behind my back talking crap on me, and they really hate me for no reason. If they just tell me they don't want me around in the first place, I wouldn't be as mad, but the last time a guy waited to tell me he didn't want me around, and we got in a huge fight, and now he acts like a ten year old girl about it trying to complain about me to his friends constantly. Apparently, I'm the only girl (or person in general) that he hates. It may have been my fault for something I said, but I know it's not all my fault.
