I hope SR gets some serious therapy. That’s the only thing that will detach her from Borce. I agree with others that he is a toxic Narcisscist and I actually feel a little sorry for Sarah. She would have been literally groomed by him since birth.
Karen would initially have been his ‘supply’ but as with most NPD victims over time they get worn down by the Narcisscists constant need for admiration and the game playing and manipulation, the little jibes and put downs, the gaslighting and destruction of any close relationships, the lies and deceit. The Narcisscist has to then work harder to get what they want so they often turn to others to get that supply. It’s common for them to have affairs or use their children as supply.
When you are no longer their supply you literally become nothing to them. It’s called ‘the discard’. This is when they show you the real them. But never in public - they never want others to see - they will continue the benevolent and wonderful act in public although astute people can observe the and often read the signs of what is happening.
Sarah would’ve been extremely damaged by her long term exposure to him. She will never recover on her own. She will continue to buy into his narrative and be groomed by him, even from jail.
He will initially not do very well in prison because he will feel himself too good to be in there, he will look down on the others and hold apart from them.
Over time will use his skills and gather a group of cronies in jail that will buy into whatever story he concocts. He will be the centre of that group and his games will
go on.
