I think you are spot on Smiles. Your ES's wife, is true to form isn't she.
Narcs are indeed just like vampires, they feed on their victims for supply. They drain them until there's nothing left and then they discard them and move on. The Truthteller as crucifix is a brilliant analogy.
Or to use another analogy, we might say that authentic people are like kryptonite to narcs. We are their weakness, because not only we can see right through them, unlike the child truthteller who is trapped with a narcissistic parent, we authentic adults are not scared of the narc. They dont have a hold over us, so they can't hold us to ransom, unless we give away our power and let them.
Narcs cannot easily control people who see through them, especially when the intended victims are secondary targets (work colleagues/family members) or tertiary targets (acquaintances or people they come into occasional contact with.......waiters, bar staff, taxi drivers, shop assistants).
Secondary and tertiary targets usually have little to lose so can (relatively) easily either disengage or at least limit contact with the narc.
There are exceptions of course .....work colleagues with whom you have to engage or family members who are closely related and live under the same roof so there is no escape, the narcs children or siblings, or close relatives of the primary principal victim. (Usually the Parent of a son or daughter who is the PPV).
That's why the narc has to isolate the PPV who is usually their partner or spouse . They have to keep the PPV away from their families and friends so as to ensure that they (the PPV) are kept in the dark and never get to understand their tormentors true nature until it's too late.
And yes, the narc will inevitably try to shift blame....."look what you made me do".
The sad thing is most narcs, unless they are very high functioning, don't even realise what they are doing. And which is why they can be such convincing liars. They genuinely believe they are the righteous ones, they have done nothing wrong. They are always in the right, and everyone else is out of line. In their minds they are the victim.....the world is against me, it's not fair, I never get a break. They are delusional.
The extreme high functioning narc on the other hand knows exactly what they are doing but just doesn't care. They know they are wreaking havoc, breaking hearts and destroying lives but they don't give a monkeys. They do it because it gives them satisfaction.
Violetsky.....Dr Ramanis videos are brilliant arent they. She knows her stuff and explains it all in a way which the ordinary lay person can easily understand. I recommend them to anyone who needs to get a handle on the subject.
Then p, for advance study, I can a psychologist called H.G. Tudor. Just Google for his website or go to You Tube for his podcasts. He maintains that he is an Ultra Narcissist, high functioning and that he knows exactly what he's doing.
Tbh I'm not sure whether he is a narc or not, or if he has just assumed a narcs persona to get his message across.
Whatever, he is very clever and intelligent, obviously extremely well educated and I would hazard a guess by his speech from a wealthy and privileged background and that he understands all about power and how to wield it.
However, he is an absolute scream, his podcasts are hilarious but not just that, they are bang on the money. . I don't think I have laughed so much as at his podcasts. Having said that, I would hate to cross him because his humour is dark, sarcastic and biting. But.........credit where it's due, by golly, he knows his onions.
His series where he dissects the relationship between Harry and Megan is a masterclass. His language can be bit "ripe" but if you want to learn more about narcissism I doubt there is a better teacher.
What I really like is that he is British, whereas a lot of the online psychologists, like Dr Ramani are American. Not that there's anything wrong with that, but I think there are quite significant cultural differences between Americans and Brits and therefore there is quite a difference in the behaviours by narcissists here in the U.K. and those across the pond.
Tudor's use of English is up there with the literary greats and he uses a lot of idioms, sayings and phrases that are unique to Britain.
I cannot recommend him highly enough, you will be both entertained and educated.
