help. there is this guy?

loved him since i saw him which was last year., and now were in the same class again this year, his white, blue eyes , blonde hair. so i asked a "friend" to tell him that i like him . she did. he said he knew and laughed. i was happy and i wanted to write him a letter of how i feel. i gave it to him he said that he had i girlfriend . than my " friend" said ." i new it all along" . that REALLY PISSED ME . because if she is really my "friend" she would have told me.i was so embarrassed. she has a boyfriend i don't know why she flits with my crush then . i mean she flits with everyone. (like you just can't trust people these days) i was really down and hurt because i thought he didn't feel the same way bout me. my other TRUE friend noticed. they were really sad seen me me like this. so they ask my crush and he said . but i have a girlfriend. they said at least he didn't rejected me. i can't stop looking at him i mean i love him. now that he came into my life i don't know how i would live when he gone. he looks at me too. one of my closest friend said that he doesn't like black girls because they are ratchet. but i don't think of that because he doesn't acted that way around me. i cried a lot i just don't know that to do. i mean i get that he has a girlfriend . he is not a jerk. please help.
