It sounds like you have a lot of your own happiness tied up in other people. If you can learn to be happy with yourself, your next relationship may go better. And even if the next one falls apart, it will be easier for you to forgive that person and move on.

What I hear you saying with this recent relationship is this: you're angry with this girl because she hurt your feelings. And she got with you initially because her feelings were hurt by this other guy, whom she eventually got back together with by hurting his feelings by being with you.

Every person you describe in this situation is focusing on their own feelings and not those of the other two, behaving in a reactionary manner. ie. "I'm hurt so I'll do X to fix my hurt." You treated her well, she left you, so you're gonna post here about how she's a bitch.

But chances are she's not such a bitch, and that her reasons for sharing time with you and eventually leaving you are not as simple as revenge or jealousy, etc.

Anyway, I agree with some of the other posts: putting someone on a pedestal is no better than treating them poorly. It's uncomfortable to be in a position where you feel you can do no wrong in the eyes of another person.

Everyone wants to finds someone that they relate to and who relates to them, and if you can only operate at the extremes of viewing women as either bitch and goddess and avoid the nuance of everything in between, you'll probably find yourself in a similar situation again.

Just a few thoughts for you, and not a putdown. I wish you luck in your future relationships.
