oh man can i relate .something like this happened to me just a few months ago. i had this chick who a few years ago had bigtime oneitis for. after ignoring her for a while things started to click. at the semi formal in january, we had a great time dancing with each other, and the time i didnt spend with her, she would appear out of no where and grab my ass. the following week or 2, she would come up to talk to me before each of our 2 classes we are in together. i was pushing all the right buttons. kinda ignoring her somewhat, despite her yelling my name everytime she passed me in the hallways. i was in complete control. then, it turns out that someone told her that i used a pickup line on her to dance with her at the semi. i found out about this because someone asked me about it. i was just like,"what are you talking about?". someone told her for some reason that can not be explained and she no longer talked to me. i knew something was up when she stopped talking to me. in the following days and for just a couple weeks i thought about what i should do. at first, i wanted to talk to her about it. but then, i just kept telling myself that im better off without her. and it works. i think about what our relationship would be now if that never happened almost every day. its hard not to when youve had massive oneitis for a chick for so long, gotten over it, and get a second chance.
today, our relationship is weak. we hardly ever talk. ive noticed how she wants a friendship with me, cuz she thinks i want her. she waited for me one time after class a few weeks ago. i teased her and made her laugh. but i can just tell that she wants nothing more than to be "just friends". i could just feel it. but thats not what i want. i now want nothing to do with her. id go for her again if she wanted me. but as for right now, we pretty much have no relationship. we havent had a conversation in weeks. and ive nexted her bigtime.
as for you, i would say that if you just ignore her for a while, she might come back to you. in my opinion you can only prove that you dont need her if you can prove to her that you are doing perfectly fine without her. the best thing for you to do would be, if you can, is to get another prom date. that way shed see that you have no problem not being with her. good luck
