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

We dated off and on from when we were 15 to our sophomore year of college. we lost our virginities to each other. I broke up with her because of the distance. She texted me last weekend because she lives in my area now, and we got lunch today. I had fun. It was a little weird, but not in a bad way. It's not like I'm still in love with her or anything. But every impediment to us being together (at least for me) isn't a factor any more, and while I've had girlfriends since her she's still the only person I've ever told I loved them besides from my parents. We're different people now though, and she just got out of a long term relationship. 

I don't know if it'd work. I don't know if she'd want to try. I don't know if she's still in my league. Honestly, I'm kind of  thinking it wouldn't happen if I tried. But I have to try, right? My chest has felt tight for days and I'm super keyed up. I don't want to keep feeling like this. She wasn't in my life before today and it wouldn't be the end of the world if we weren't friends.  I don't want to make a fool of myself though, and I'm also worried I'm getting caught up in the idea of something that's not necessarily based in anything real. What should I do?
<bot>: I don't know if I can be friends with my ex, but I'm worried that I'm getting caught up in our history and not looking at things objectively.
