I had a crush on this girl all of high school but never really knew her. Then we had a few classes senior year and sat next to each other in both of them. We immediately hit it off and for the next 4 months we got really close and my little crush had developed into a huge one and I really caught feelings for her. I tried to make it clear I was into her and she showed all the signs of liking me back, friends of ours said she did, and I even got asked twice if we were dating. Then in December my feelings for became open and she acted a little surprised and told me she liked me but was not looking for a relationship at the time for a couple of reasons. But then she ended the conversation by saying "I hope you understand I am not crossing out the future between us". I thought it was a clear rejection at first but when she said that I thought I still had a chance. SO for eight months, I dealt with her and the whole time I figured she understood I still liked her. But either she forgot or she is a spineless b*itch because I was really friendzoned the entire time and knew it when she came to me about her and another guy having sex and the condom breaking. Apparently, I was the only person she felt comfortable going to it about. The next day, I snapped and told her I did not want her in my life anymore and we graduated a week later.
She has tried texting me a few times this last month to save our "relationship" but I shut her down last time she tried. She still favorites my stuff on social media. And we are both going to community college next month and I will most likely see her there a lot and might have a class with her since we are at the same intellectual levels. I won't be able to avoid her then and I really do not have a clue what to do if she tries to say anything to me if we do see each other. One of my friends even thinks she might actually want a relationship now the she sees what she had and misses it and all that other crap and to be honest, I don't know if I would reject her if she tried. I hate her for what she has done to me and do not want her in my life but at the same time can not stop thinking about her and feel like I still have feelings for her. Any advice?
