<human>: My girlfriend and I broke up almost a year ago. At the time we were both 16 and are now both 17 and in high school. For a few months after that she told me she didn't care for me and a whole lot of other things. I was desperate and I tried my hardest to get her back, but had no luck. I was distraught to say the least. Then one day I met another girl and I started to like her and show some interest. Somehow my ex found out and started talking to me again. Which led to me focusing a lot of my attention on her again. I was sucked back in and back at square one. 

This trend kept on happening up until a few months ago. I had made up my mind and said I was done with her and I was going to move on. Once again, she found out about this due to mutual friends. She wrote me a letter saying how she still loved me and would do anything to be with me again. I was foolish and agreed. We kind of dated for a week and I had to call it off because I was just so confused on how I felt. We remained fairly close, but argued a lot for the months to come. About a month ago she met a guy and has since started dating him. Before that though we were really close and I had even thought about trying again. I felt terrible. I tried to just cut ties, but since I see her almost everyday that wasn't very easy. Not too long ago we got close again, probably a few weeks back. Then the same thing happened.

I can't just keep going through this back and forth stuff with her. I do care about her, but I just can't take much more emotionally. She's moved on and I need help doing the same. I would really appreciate any advice you all might have
