What Should I Do?

Well it all started maybe a year ago. My friend introduced me to this kid on myspace and from there we started talking.

Our personalities clicked instantly. Then a couple weeks later i met him in person at my friends house and we talked and flirted. Ever since that day, i would hang out with him and my other friends almost every weekend since he went to a different school from mine.

I figured he liked me because we would always flirt and hangout plus he kissed me on the cheek one day before leaving.

Then one day i was at the movies with him and other people and then from that day he stopped talking to me. He wouldnt answer my IM's, messages anymore.

I tried for so long to try and ask him what's wrong or why and he wouldn't answer me.

My friends also tried to talk to him about it and he would always change the subject. I feel stupid for still having feelings for him but i just can't help thinking about how things used to be. I miss him alot.

But now i've been dating this kid for three months and i'm happy but i'm just confused on whether to stay with my boyfriend now or try and work things out with the other kid.

I dont want to risk my 3 month relationship for something that might not even work out. But at the same time i feel more physically attracted to the other kid and i really miss him and the way we used to be.

I've seen the other kid recently at a birthday party and we didn't really talk but he noticed i was there. Just seeing him gets me thinking about my feelings. I'm really confused.

I've been confused for a long time and i really need help. please give me advice on what to do. Thank you.
