What you're describing is attraction changing, waxing and waning, which is what I said. At this very moment there is no attraction between them. Yes, that can change. You said the attraction is still there, which if true she wouldn't be pushing him away. It might come back, but right now it's not there. You said it yourself, his behavior has turned her off.
I separate attraction from being a man/woman. How I define it:
Attraction is physical attraction and chemistry. It is what literally draws people together, usually in a matter of seconds.
Being a man means to know oneself to the core and being in contact with oneself. Every other manly aspect is obtained as natural consequence or by natural development from that. This should be a baseline.
Being a woman: I don't know.
But the FFF protest girl is not a woman, and a man not enough in contact with himself is not a man.
So the aversion comes from not being a man/woman, not because someone is ugly.
The separation is very important, because it explains the mixed signals you receive after a rejection, when there is high attraction between you and her. You can trust the attraction is staying the same. Now you have your ease to restore power and respect. Her emotions are fleeting in this time, her opinions about you as well, but the attraction stays. After you have restored enough power and respect, you can start building a connection again, to the point of time that suits you the best.
I've had plenty of beautiful women where I felt aversion to the point of permanent turn off. At a point of digging her own hole, there becomes little point in keeping track of how deep she's digging. To ignore past slights is again a manifestation of a lack of self respect. To build on your example, if she lies to you repeatedly are you going to keep forgiving her indefinitely if she's sweet afterwards and says sowwy?
Exactly, OP pretended to be confident and now his boss has enough.
But good point about the girl digging her hole and ignoring ones own anger. Usually rejections are done hurtful by women, so unless she is making up for it or punished enough by indifference, she can keep sitting in her hole.
