If crying isn't a "turn-off", then why is it when a guy cries after he gets dumped the girl pretends?

Girls want a sensitive husband!! Sounds like you are in the dating stage. If a girl dumps you and you have the "whatever" attitude, she doesn't feel terrible every time afterward that she sees you. If you cry, she knows that she hurt you and doesn't want to pour salt in the wound. That is why she will run the other way. Keep your chin up. Maybe one of those girls will realize they made a mistake.
