I pretty much agree with >>2: It's tough luck that she felt attracted to your friend and not to you, but it's no one's fault and you should not hate anyone over it. You basically managed to go out with her because you were there when she was vulnerable after being dumped. But very quickly she realized she does not love you and did the only sensible thing to do, which is to break up with you.

Although I understand that you feel angry, you must understand that you have to actual right to behave so. If you continue to display aggressiveness to her you will just end up more alone and spiteful. Just accept that the girl is not for you, and check out other women. There are plenty to choose from, and others are probably better able to make you happy.

Imagine a girl was still chasing you and at the same time bashing you when you made it clear that you are not interested in her. Wouldn't you end up finding her behavior pathetic and be even more repelled by her?
