So my ex and I broke up a little over a year ago after being together for almost 2 years. Long story short, we got together and things were going great. We did the long distance thing, well kinda, she lived almost 2 hours away going to school and we did that for over a year. I decided to transfer to her school for various reasons but her being a major factor in that. About 3 months after I moved here we broke up. We broke up for a lot of reasons but it was her idea and she said that didn't treat her like a gf anymore and we became comfortable. Naturally I was devastated but we kept spending a lot of time together, sleeping together, having sex, etc until the summer came when she left to go to NC for the summer. She started dating someone during the summer and I did the same. She got home and tried to do the long distance thing with said bf but didn't work out for various reasons and I ended my summer relationship because I saw it going nowhere. So we move back to school and kinda spend a little time together and I meet a great girl and start spending a lot time with her and stopped really talking to my ex all together. Things kinda got serious with the other girl but fell apart at the end of the semester and the ex starts calling again wanting to hang out. So over xmas break we do and such and it's just good company but she flirts all the time and tends to bring up the past relationship and the cute things I did for her and such. (A little background on the ex is that I bought an engagement ring for her before we broke up, I was honestly head over heels for her and we honestly talked about a future together.) Fast forward to now and she keeps making comments about things and flirting and I really don't know how to interpret it. I admit to you all that I still care about her but I don't know if I want to get in a relationship with her again because I don't think I can bare to have my heart ripped out again by this girl. Is it just a control thing with her or does she think that there might be something there? Any input would be great.
