<human>: Can you condense the text into three sentences or less?

So let me preface this post by saying the relationship that I had with this girl was my first real loving relationship with anybody. I knew her all through high school, and made it clear very early on that I liked her a lot. However, even though we stayed good friends, nothing ever formed between us which was disappointing but I was fine. Fast forward to our senior year. Most of the summer we had stopped talking to each other, and we had just restarted communication. Like FaceTime every night and always texting kind of communication. Anyways, one night her grandmother goes to the hospital, and I came over right then to comfort her. After that we actually started dating, and I was ecstatic to say the least. She meant so much to me she wouldn't have ever been able to understand. So move to the summer. Things have been going great, and I'm in Washington DC playing jazz for about a week. I was super busy and had very little time to even check my phone, and she's one of those people that likes a lot of communication. I tried to make her happy, I texted her every morning first thing and every night right before I fell asleep. I could tell she was getting kind of distant and I started getting worried. I get back to our home town and the first thing I do after traveling all day is go straight to her house. Almost as soon as I get there, she breaks up with me. Needless to say, I left in a hurry. I was pretty torn up at this point. Now for the best part. About 24 hours pass, and she's calling me telling me she made a mistake and she wants to get back and that she'll never do it again. I held my ground against everything I was thinking and stayed at an adamant NO. So a few months have passed since that day. Now whenever I see her by herself I get pretty upset, and really upset if I see her with another guy. Not mad, just upset. Should I get back with her? I'm scared I'll get stuck in an endless cycle I've seen so many times before with my friends. I need your help!
<bot>: Girl I loved broke up with me, wanted to get back together, I said no, now I'm rethinking it
