I AM SO IN LOVE WITH HER...BUT SHE DOSE NOT LOVE ME...

Well, i love this girl named...lets call her kim. & she is soo perfect, she is beautiful, caring, nice, smart, i could go on for ever...but the thing is that i am a girl...thats why she dose not love me this same way. She is one of the 4 people that knows i am gay. & we are like best friends. but thats all that she would ever allow...even though i would give up the would for her. (by the way i am in the 8th grade). & the thing is i found out that last year she dated another girl...but she wont tell me. she dose not think that i am trust worthy for some odd reason. i have done nothing to make her think that way. but it hurts me soo bad to know that she can date that other girl, but tells me that she wont date me because i am not a guy... and yeah she has a boyfreind this year, and it made me wont to cry everytime i saw them kiss or hold hands in the hall way. but i was there for her when they had problems and i always told her that i was happy for her when there relationship was going great...even though i was secretly diying.and yeahs she knows that i like her, but she has no idea that i am in love with her. the school year is almost over, and we are going to different high schools next year. soo i wont her to still her to be in life no matter what. but i dont know i am soooo in love with that girl. and i have had 7 girlfriends all ready...and i am pretty good looking (i think so)....so i have no idea what i should do. i love her, she is liying to me telling me she is not like that but has dated a girl before (whitch killls me), and i am not the most popular person at school but i am not a nerd eather. so why wont she have me???? sigh...sometime i wish that i never meet her, that way i would have never fallen in love with her. :(...PLEASE GIV E ME ADVICE ON WHAT TO DO...
