I see a lot of people trying to over-complicate this, but it is really super simple.

If the guy wants to either violate you, hurt you, or show aggression or anger towards you for being rejected, then he is acting entitled.

If he still respects you even after you turn him down, then he's not acting entitled.

That's the difference. It doesn't matter if the guy "feels he is owed something" or "feels he deserves something" or not. That has nothing to do with it. He can feel all those things without lashing out at women if he can't get his way. If he isn't being mean to you, he is not acting entitled.
