You don't expect a prostitution to know the worth of money.

You don't expect a woman who's ino hookup to appreciate the little sacrifices you're doing for her.

You don't expect a woman who has slept with several men not to feel entitled to a man's money.

You don't expect a woman who has never worked genuinely for her money to be appreciative.

So, that your woman who's feeling ungrateful and entitled is probably into hookup, which is why she doesn't see the little you're doing for her as something.

Cut her off immediately!
