How should I get over or even with someone who hurt me?

I asked a really nice and smart (I mean like genius, seriously) girl to a dance last year. We were friends at the time and I asked her so I could know her better and I wasn't planning on a serious date. I was really nervous when I asked her and she knew it. Anyway, she said she would go with me, then blew me off. (She said she was busy before the dance, but went to dinner before the dance with friends.) But what really got me was that she blew me off at the dance. She pretended she didn't know me and grinded with a random guy (I totally thought she wasn't like that because she is really nice to everyone, plays piano at church, and goes out of her way to help people) Anyway I get upset sometimes about it and it hurts me to talk to her, even a year later. It always bothers me when I talk to her and I ignore her for weeks at a time then suddenly start talking to her. I hang out with other girls, but I can't seem to get over what she did to me. I had a couple plans in mind like talk to her about it or get revenge somehow, but I wasn't sure what to do. Any advice or suggestions? Sorry for rambling...How should I get over or even with someone who hurt me?
Well one thing you and I have learn, is looks are quite deceiving. The way people come off, the goodie 2 shoes ones.. I had to learn the lesson years ago. She is a fake, church girl grinding @ a dance give me a break.. She appears to be very selfish and gets off on disappointing people. Anyone that acts like they don't know you, then you need not to know them. With all the bad crap inside her dude move on. Even giving her the time of day is doing her a favor. I mean she has not even apologized.. But getting even will make you no better than her. When she comes around go in the direction, Give your attention to other for real girls, stop wasting your thoughts on this loser. And keep in mind, what goes around comes around. She will get hers but don't let it be by you.. When she sees your interest in another female that will screw with her. And then you tell her to where to get off. Good luck dude....How should I get over or even with someone who hurt me?
i understand that she hurt you ... but dont get even it is just going to get you in trouble she is not even worth it .......what you need to know it that it dont matter how mad you are at her it dont mean anything to her or she dont know that she hurt you first of all you need to forgive her and if you need to talk to her , tell her that you have foregivin her and you just need to tell her that she hurt you ...... and how she hurt you .........
I hear where you're coming from. First of all and most importantly; it's unhealthy for you to harbor these feelings of resentment toward her. You're only hurting yourself and it's important.that you realize this. Secondly, it would seem to me that this person is a phony and really isn't worth any of your consideration, your time, or your thoughts. There are, as they say, ';many more fish in the sea'; . My suggestion to you is that you say nothing to her. And revenge is not an option. It will only bring you down to her level. I'm sure you will find someone who will help you to forget all about this unfortunate situation. It may seem difficult now and it may take some time but believe me, the sooner you employ this idea the sooner you'll look back and laugh. Best of luck to you.
