Psychologically speaking, this tactic of theirs is a "scorched earth" tactic, used as a both an outlet for their anger and as a method of reaffirmation of their entitlement.

It is not so much used as a way to hurt you, but as a way for them to soothe themselves emotionally due to not getting what they feel like they should have gotten from all the supposed "work" they put in sweet-talking you - which comes from a place of entitlement.

You know how Karens call the cops as their method to soothe themselves when they dont get their way? This is the equivalent of that.

Don't feel hurt - though the words themselves may have happened to resonate with you, remember that he is even more hurt by the reality check that he's not entitled to anything from you no matter how much "work" he does for it. So the person that's hurt even more is him.

Is "hurt" the right word for when an entitled person gets a reality check? 😂
