Best boyfriend turned on me?

i am a very girly girl but i hav a lot of friends that r boys whch i dont know why but theres this one guy who has been my best friend forever. (since 3rd grade) now we r in 9th grade and i am pissed becuz he totally turned on me. he ditched me for the populars and now he is a total jerk. i didnt realize it at the time, but i sat next across from him on the bus and he was just talking about everybody in such harsh terms. i ***** take it, and apparently he was eating a red bull and talkin to his friends and i guess they thot it wud be funny to leave the empty can on my seat wen i wasnt looking. fortunetly i was listenin to their whole convo so i know they did it. so i threw the can at them and he bitched on me. believe me i told him off but i just want my best friend back
