I like him. Im confused. It hurts. Please help.?

Ive liked this guy for about a year and when I first met him, we would talk on msn and stuff and click instantly. He would flirt and stuff and would always start a convo with me as soon as I would appear online. Then strangely we just drifted apart. He got a gf and I would say to myself, "okay im officially going to get over him". But everytime I would say that, I would always bump into him. And obviously that really rollercostered my feelings. This happened twice. Then I met some other people and eventually moved on, but I always had a feeling inside of me for him. Then after what felt like months I finally saw him on the bus and we started talking. He broke up with his gf and I dno. He kept tryin to talk to me. But what really got me hurt was, earlier that day, he met up with one of my good friends Kelly* and her friend. Kelly*'s friend knew the guy and they just bumpoed into each other at the bus stop and started to talk. Then Kelly's friend, Jess* introduced Kelly to the guy.
