<human>: Can you summarize the given text in a few sentences?

So, I dated this girl for two years. Shortly after the first year, she had to move across the country (US) do to parental reasons. We stayed together for another year, but eventually either the distance wore away at us or maybe I didn't call enough and we broke up with a loose agreement to try again if she ever moved back. Well, fast forward a bit and she's back around. She goes to a different school and started up a relationship with a guy, but they recently broke up. We've seen each other every now and again, but remain in touch largely through text, FB, etc. It just sucks to know that it seems there's no chance of what we had ever happening again, and I don't know if (or how) I should express how I feel or if I should just try to move on.
<bot>: Dated a girl, she moved, we broke up, she came back, now stuck with feelings I don't if I should express.
