Guy help please!?

Okay so there is this guy that I realllyy like..and I have noo clue why I have such strong feelings for him...I just met about 2 weeks ago and I thought liked me...he seemed like he was flirting and we went with a group of people to the movies...and he held my hand and all that cute stuff...but sometimes when I would text him he would respond but after a while...he just stopped mid conversation...or sometimes he just wouldn't respond at all......soo I was curious and asked one of his friends if he thought he liked me and he said he didn't think so...which really really hurt me....and I don't know what to do...it's the third guy in one month that's turned me down...I don't know what's wrong with me....I don't think I'm the hottest chick ever..but I'm not ugly either..at least I didn't think so....you can go on my myspace to see a pic www.myspace.com/kha35 and give me your opinion...because maybe I'm wrong..but should I ask him myself and possibly cause more heartache than I already have
