They lie, they manipulate, they abuse of their power (school teacher that hookup with a student), they use drugs to look confident and they drug the woman to sleep with her.

IN SHORT THEY HAVE NO CONFIDENCE AT ALL, CONFIDENCE IS A LIE A LIE A LIE A LIE A LIE. The woman doesn't want to admit that they fall for a man for his money (don't want people to know that she is a goldigger) or his drugs (doesn't want people to know that she is an addict) so they will use the "confidence" card.
