In the passage the narrator most likely told the girl to stop being selfish, at which she laughed at and then left to go somewhere by herself. Femininity and youth are out of the question because we don't know her age and there's no suggestion or statement that links the woman's actions to her being young. The same goes for femininity - no hints or statements linking her leaving to being a woman. That leaves identity and betrayal. With thorough thinking and analyzation of the passage, the best guess is betrayal
