If you ask a narcissist not to do something that violates your boundaries, they will keep doing it, and every time they will act surprised when you still don’t like it.
But the reality is, they know you don’t like what they are doing, and they remember that you told them. They are just testing your boundaries, and making sure you know they are purposely disrespecting you. They are also gas lighting you to play games with your head and make you doubt your boundaries.
Since they’ve already been asked to stop, I no longer bother to correct them. Repeating myself is only continuing to play their game.
