When our hearts get broken, suddenly everything gets generalized. You feel a woman did you wrong then clearly all women are wrong-doers. If a man behaves like a dog, then clearly all men are dogs. We love so specifically and then hate so generally.
This seems to be inevitable – at least in heterosexual relationships.
Certainly a woman who’s had her heart broken by a woman might still indulge in a lamentations of “Women! Can’t live with ‘em. . .” but there’s always in reserve the self. If it’s included, it includes a measure of self-deprecation, self-mockery, self denial.
Woman’s love is just as long and just as short as man’s is. Depending on the people and the circumstance.
