Do I have a crush on him?

Well there was this new kid in my school, and a month after he moved here - we started hanging out. But I already like someone, and my friend (new kid in school) became friends with my crush, and my crush and I barely talk to each other. But after me and him started getting closer, I asked him who he liked and he said he wasn't going to tell me. A couple of weeks later he finally told me and a week later he and his crush started going out. Then my best friend told him that she liked him so he broke up with his girlfriend and started going out with my best friend. But lately - I don't know but for some reason I want him to like me. And everytime I see him and my best friend together I get jealous, I don't know if it's because I like him or because I don't have a relationship for my own. And my other friend saw him and me walking down the hallway, and when he left she said that we looked really cute together ... and it just put the bigggest smile on my face. But I don't know if I like him or not, I still want to like my crush because everytime I see him I smile as well. I DON'T KNOW MY OWN FEELINGS - please help me

well in my opinion, it sounds like u'r kinda jealous ((but not really)) because you don't have a relationship for yourself......don' t worry I feel like that sometimes & I'm single. but don't try to rush into anything....like, don't hook up with anyone you don't have feelings for just to be in a relationship!
