should have let my gaurd down

i never dared to like someone when i was younger, because if i did he would break my heart in the end. I kept my feeling burried and didnt let anyone get to it. since my highschool year started i have had a crush on this boy for the longest time. For a while i thought he was into me because he would always give me a compliment and grin and tell me i was pretty in my own way. in his words" your pretty because you different and you have your own style and attitude." that was just after i sed i wished i was cute and popular like he is. So i finally let down my shield and let him get to me, but then like usual something came up. i thought i had a chance for once.

[COLOR="Red"]I noticed that he would always walk with this one girl to the stairs, but nothing ever happened until today. He kissed her so i walked away. I didnt care for that but only the fact ever since that he never talked to me the same.[/COLOR]

all i want to know is why can't i ever have a guy, just one, that would kiss me like he did to her? Am i not pretty enough do i need to be that kind of slut that lets anyone do anything for me to get some love. If anyone ever had this problem i would appreciate hearing it. i don't want to be the only girl that feels this way.
