Please, Seiken3... For the sake of your mental health:
Take a step back and allow yourself time to heal. Of course it hurts; giving up on a wish is always painful. But there's plenty of people on this world who aren't as messed up as this person is, and quite a lot of them are good for you. Quite a lot of them will find you attractive for who you are. This person isn't the only one, and she'll only end up hurting you. Time and time and time again.
Please don't go there.
