You know-- I understand this feeling. It hurts your pride, maybe, that this was not your choice and that no matter how great you are, she doesn't want you. That is one way to look at it.
But there is another way to look at it. Maybe she is not all that great. Maybe you deserve someone better. You'll never get the satisfaction or "triumph" over her. But-- you might just end up with a really awesome happy life, a partner who deserves you, etc... if you can take a breath and let her go. Say good riddance. It may be the hardest and best thing you'll ever do.
