<human>: Can you give me the gist of the text in a nutshell?

I don't think there is a right answer here because it is a complicated situation. I was never dating this girl but we were on and off for a few months, then we were on, and then we got pretty intimate, but decided not to officially date because she was abroad mid Feb-late May. She came back and we were very close again, but we ended up across the country over the summer. We agreed to take a break, but continued to talk every day because of how close we are. For the first half of the summer, I was talking with and going home with other girls (when super drunk,) but it made me feel shitty and just miss her. I fully intended to date her come fall. Midway through summer she told me she met a guy, but didn't want to take it past the summer, it was just a fling. But it hurt too much to me. She met this guy after like 2 week and started hanging out with him. Physically being something and emotionally being with someone are in two different ballparks in my opinion. Sex is sex but establishing a mutual trust and caring for each other is different. I told her i didn't want to talk to her for a while, and deleted her number so to not be tempted to text her. I ended up meeting a girl here and have been casually going out with her, and she has helped me to "move on."

Here is where my issue comes in - this new girl is just a summer fling. I leave in a few days and have 0 intention of carrying it forward. I don't know how to approach the girl i had been seeing, or if she is still talking to this other guy, or what. I want to handle this in a mature way, because we were both distanced for a while. i am not even sure i want to get back together (or if she wants to.) Christ i don't even have her number to text her. 

Any level-headed advice would be appreciated
<bot>: a girl and i have been on break and have seen other people. We will be reunited for the first time in months and i dont know how to proceed
