Most Helpful Girl
Maybe she craves the drama or the attention she gets. Maybe her leaving a guy feeling vulnerable makes her feel a since of empowerment. I know quite a few girls who could have had insanely good relationships, however left men who cares for guys who couldn't give a fuck if they hurt her. Maybe she was just in it for the fun and actually realized that there was work that needs to be done in a relationship and therefore she wasn't ready to take on such responsibility so she left. There is also some faz that certain women go through that they find themselves in love or in extreme attraction to another guy who smooth talks his way in then leaves her hurt. Its instinctive to go for the other guy, so clearly she wasn't thinking. It happens quite a bit, and frankly it pisses me off but it happens and there isn't much he or others can do. Its a mere crave for drama and attention rather than sincerity. There isn't a direct answer to such an occurrence, or motive, but for sure 99% of the time it's attention, especially if they were young.
