Saw this thread on r/niceguys. Now I know the definition the sub works on that a guy is nice until he gets sex and then acts like an asshole.

How does protesting about not getting appreciated a trait? Now in the comment section it said it's basic deceny to do such things but also a basic decency to thank them. If someone does stuff for you, you should appreciate them. And then don't women complain why guys don't get appreciated or act as a gentleman anymore. I am just trying to wrap my head around this.
