If she dumps you, you have to let it go. She made her decision - assuming she's at the age of 16 or older, she had very good reason for letting you go, so it's something you have to live with. I know it sucks, but that's the straight-out truth. If ever you want to go out with her again, you need to make her like you again, but DO NOT SEEM DESPERATE. Good luck.
