Wont it always just be me?

a boy i really liked so much.its totally different than what you think, i know you think im just a stupid teenager with my hormones out of control but thats not what its like at all.so anyway, this boy.i've liked sooo many boys before but this one is the only one that i actually felt chemistry with, and i mean real erflies-in-stomach chemistry,i think he almost felt it too..but we never got a chance, when i almost mustered enough confidence to do something about, i found out he had a girlfriend, but he got this grlfriend way after i met him, which means way after the chemistry, so i guess that means he didnt feel it too. i listen to that song for beyonce 'irreplaceable' and it makes me cry cuz i know thats not true with him,i cant replace him or have anyone like him then i listen to that song for whitney houston 'i will always love you' and realize how depressing my situation is... so then i finally tried to forbid myself from thinking about him but that didnt work, what do i do???
