How can I get over this girl I really liked?

So I liked this one girl from 6 to 8th grade. In 6th grade she didn't like me back but went out with a whole bunch of jerky guys and I was always there for her. In 7th grade we became closer friends but she continued going out with douches who broke her heart. I gave her my shoulder to cry on graciously. I always gave her advice. Finally in 8th grade she liked me back. We started to get really flirty and hung out more and really had fun together. We never offically went out but we were an unoffical couple. Her ex started talking to her again and she forgot all about me. We ended middle school as just really good friends and now we go to different high schools. I still think of her all the time though. Sometimes we text and hang out on the weekends and she told me her and some friends were talking about how much they loved me one morning. Whenever we see each other or hang out at a friends house we sit close and next to each other and laid out on a trampoline one night with just each other and talked looking up at the stars. I still like her and get nervous whenever she hugs me. Do you think maybe she likes me again too? If not, how do I get over her? I honestly love her with all my heart but I'm tired of the pain. How can I get over the pain she left with me? Thanks in advanced.
