Story that leads to question:

Guy meets girl, doesn't have to use much game, she is naturally attracted to his type. Girl chases after guy hard and works extremely hard to win his favor. Guy uses alpha friends to test her loyalty (free will) by having them go undercover and hit on her. She passes test. She successfully wins LTR and they feel a strong passion about wanting to make one another happy and are empathetic for one another.

Few months later: guy goes to college and girl is infatuated with him. constantly trying to win him over. Guy is paranoid that distance becomes an issue and she will cheat (seeing her more as a drone than a unicorn). Guy accuses her of cheating and resentment starts to build within girl.

During the months of building resentment: Guy starts becoming self aware of having no training in the red pill field and thoughts start to linger that he isnt good enough. Insecurity builds and manifests itself in his interactions with the girl. Guy tries using red pill tactics in LDR (dread game.. cold shoulder, jealousy...etc.) Girl cries a frequently is very hurt "by him not trusting her and not caring about her"

towards the end of relationship: guy visits with his girl every two weeks in LDR to have sex. Girl constantly tries to win his favor. last 2 weeks of relationship: girl has pent up anger from guy continually showing distrust and using dread game. She is still so wet for him she is constantly trying to win his favor. Guy uses dread game and goes back to visit girl. She dumps him out of much anger and built up resentment. She still is attracted and hopes she will stop being hurt all of the time and wants to get back together. then she decides it wont change.

Question: why did this happen?
