18 Year Old Guy And Heartbroken?

So, let me fill you in on a story of my stupidity. My name's Nick, obviously. Six months ago, I lived in Oregon. I started talking to family up here in Alaska. There was a girl that was my sister's best friend, who started talking to me once I broke my hand. After just a few days of talking to her, I'd realized that I was addicted to this girl and she was to me. We would talk for hours and I'd sing her to sleep. She heard secrets that I'd never told anyone. I got the balls to pick up my things and leave my town, partially for my family, but mainly for the girl. We didn't wait on sex, it was 4 months into our relationship and we just couldn't hold back any longer. Big mistake. Our relationship became a majority: sex. We communicated little and fought a lot of the time. I regret not keeping my mouth shut and maturing on that end of it. So, let me just cut the middle ground. Sisters' best friend. First person I'd ever said "i love you" to. We broke up. She says all these rude things and stuff about me to people. Now I just hate being in this town and hate this feeling.

As whiney and stupid as it sounds, I don't want to let go of her, but she confuses me with her saying "I don't want a relationship right now. It blahblahblah".

Do I keep trying for her? Or do I get the **** over it and move on? If that's the case, then how do I do it?
