<human>: I went out with this girl [18]toward the end of my senior year of high school. We dated and had fun for a couple of months. We really liked each other, but it had to end when her family got stationed in another state (dad military), forcing her to move mid summer. We mutually broke up because a long distance relationship would have never lasted, and would have probably ended badly. It's 6 months later, and we go to college in different states. She is in a relationship right now. My problem is that I still can't stop thinking about her, and I feel like our relationship was ended way too prematurely. I would never contact her while she was in a relationship, but could that ever be an option for me(while both of us are single of course)? If so, what would I say, and If not, how can I get over her?

Can you summarize the given text in a few sentences?
