Why would a girl i like do this?

ok so theres this girl thats in my church and shes in 3 of my cles.so last year she hugged everyone(i dont know why) except for me. and if someone asked her why not him.she would say i dont want to.and im alot better looking than some of the boys she hugged. and so this year she stares at me alot just like last year. and when her friend asked if she liked me she said ewww no. and she really seems to try to make me jealous by letting a freak put his arm around her,magicly while im around. so why do you think shes doing this? does she like me?she also talks about my favorite sport to her friends around me. why?
