Do you think this girl likes me agin?

I use to see this girl staring at me and looking over at me alot last year at school and I saw that she would get really shy when I was around. So I started to like her.( evey time I tryed to talk to her she would get nerves and her face would go kinda red and she would walk away). So than I asked her friend if she liked me than her friend said yea kinda so I asked her friend for my crushs number so than I texted her and she didn't text me back.So I gave up. Than over the summer her friend told me she didn't like me really......Now since the fisrt day of school I have been seeing her looking at me and looking back at me every time I past her in the hallways... So why is she doing this. ??? Does she like me??? Because she doesn't do it to anyone else.
