If we didn't project fantasies and preconceived realities onto a girl, our expectations would be in line with what reality is.

Let's not forget that when you're in a relationship your girl is *constantly* spinning up fantasies. It is very difficult to constantly discard them. It's not just that our expectations our out of line with reality, it's that we're being bombarded with very convincing lies, tears, poems, sacrifice. Women don't understand their own nature. They are in love in that moment, they do feel they want to spend the rest of their lives by your side in that moment, they will sacrifice their arms and legs in that moment.. but tomorrow? That bitch is gone.
