Why does she try to break me down after she rejected me?

2012 (may), I introduced myself to this girl in a nervous/blushing manner, (She knew that I liked her). I walked up to her in front of her friends and introduced myself.

But never had a chance to talk. I thought she was ignoring me in school, so ignored her on graduation last year. But then I found out that she liked me so I tried to talk to talk to her for many months but she rejected me (not desperatly). from October to December

She was annoyed by me.

Then I December I finnally talked to her, even told her that I liked her but she said that she didn't like me and told me I was weird for liking her cause we only have talked once so mentioned her that I was curious about her many months before I even approached her.

I TOLD HER THAT I WAS CURIOUS ABOUT HER BEFORE I EVEN APPROACHED HER AND THAT I THOUGHT THAT SHE IGNORED ME CAUSE SHE PROBABLY didn't WANNA TALK TO ME SO I IGNORED HER...

---------------------

After she rejected me told all her guy friends about me, so now they are starring at me they look threatful at me to... Even some girls. This girl hooked up with a guy at a nightclub when they were talking she pointed at me and talked about me. And she loooked me a lot when I was with my friends and laughed I think she tried to tease me..

!?!?!?! BUT::: When I dance with other girls she looks really mad at me... WTH

She sad bad things about me a lot of people, I actually Haven't done anything wrong.. Now many girls are ignoring me, what can I do about it...

Im not jealous, this kind of things never makes me jealous its jealous.. But I don't get it.. she hooked up with a guy, they are like boyfriend and girlfriend but she hates when I dance to other girls...
