<human>: A little backgroud: I was around 17 when we met/dated and she was around 16. We met at a camp in Boston (neither of us are from there). After the camp we just kind of kept talking and decided to try dating long distance. While I now realize that was stupid, to be fair she was really hot, at the time I didn't care. We talked on the phone all the time and we even visted each other a few times. I was her first , but she wasn't mine. We broke up after 6 months and never talked again. I think if we lived in the same place it could have been more, but it was doomed from the beggining. Fast forward to now, last time I was back home and getting some stuff together to take back to my apartment I cam across this box that had stuff from when we were dating. I was feeling nostalgic and looked her up and found her. I haven't talked to her since because I have no clue what to say to her. I don't want to date her again but I just want to talk to her. How do I approach that?
