Anyway I can get her back?

You should try to meet someone new, too. It seems to me that she was probably someone who liked more of a adventurous relationship rather than a one sweet guy kind of thing. Everyone has always had a first love, but rarely do these first loves actually last forever, there is always going to be someone new, and probably even better. Try it out, I'm sure you'll find someone worth your time. But, try to stay friends with her, she seems like a nice gal. :)
