<human>: Can you give me a shortened version of the text?

To give a little back story, I ended an eight month relationship around two months ago. About two weeks ago I started my endeavor of trying to date again with the hope that all girls aren't as terrible as my first girlfriend was (I had waited for this girl since I was thirteen and hadn't had a "real" relationship before). I was talking to three girls at the time and was planning on taking one of these girls to practice with me when her friend tagged along since they were going to the same destination. I started to really enjoy talking to her friend and after dropping off the original girl; she decided to skip a day of practice and asked if we could just drive around and talk. What started as a simple drive to a local restaurant turned into the best 6 hours of my life due to amazing conversation and the wandering into different stores just to get a good laugh. At the end of it all we did end up kissing and she actually asked me out to the movies for that Saturday. Until that day we hung out everyday for the duration of that week. I was excited. I didn't think life could get any better. 

In a weird turn of events, I forgot that the mandatory practice for a sport on the weekends had been pushed forward a week and I had to cancel. I could tell she was disappointed but I told her that I would make it up to her on Monday. Now it's a new week and she's told me that she doesn't have any feelings for me. This is where the confusion starts. Last week was such a crazy week and I could tell that she was really into me. Now she has chosen to just forget it all. What should I do? I understand that it was a sudden meeting between the two of us and the fact that we are still very young but I desperately need some advice. I've tried talking to her but she's been ignoring me for some reason. I asked her what led to the sudden change and she didn't tell me anything. Should I just forget and move on or should I pursue?
<bot>: A girl and I became incredibly close. Now she has chosen to forget all the feelings she had for me. What do I do?
