Why the Narcissist hates you BUT doesn't let you go!
Imagine the narcissist as jailor and you, as prisoner, whose existence benefits the narcissist. Your desire to escape is tempered occasionally by incremental acts of kindness, which seem to outweigh the tortuous situation, when the narcissist senses the end of the relationship; in reality, such acts are insufficient but seem to be more than enough for you… this is how the narcissist keeps you in place to derive the supply they need.
