So, let's say you are a narcissist. You date someone who gives you everything. Love, devotion, presents, lots of sex. Lots of "supply".
You leave them and then try to come back.
This time, that person won't accept you and gives you nothing. They lay down the law and say, "Boundaries. It is my way or the highway." Meaning stop acting like an asshole.
Which would you like better?
It seem to me, You would shape up and then get everything. Apparently, they feel different.
What would you do?
