As in "Main Character of a movie - camera's always on the MCS, and they have "plot armor" keeping them safe from everyone and everything"

I used to use "Little Princess" (pins the mental/emotional maturity better), but MCS is going mainstream and it abbreviates well.
The basic principle with narcs is that they
need to get what they want, which paints a target on their forehead.
Your having what
they need reverses the control. But doormats can't do that, so Narcs easiest victims need to work on their spine before acting.
Hopefully in your case, the principle is just to
selectively check them: be less accommodating when it's plausibly polite.
I'm out of time, but if you can do this
without getting caught, you can slowly rebalance the relationship.
If you're still interested, we can talk some more tomorrow (EU time).
BTW extreme "golden children" can be damaged to the point that this kind of gentle approach isn't effective.
If you think that's the case, I can't/won't help.
I don't think she's that extreme. But being Daddy's girl for so long has rubbed off on her.
I did say to her, basically, that she'll have to meet me half way. Which is me learning to put in better boundaries with her.
At this point I'm open to building a relationship with my 2.5 yr old grand daughter, and at the same, allowing my daughter to put some effort into our relationship, built on reciprocity, from here on.
Myself and guyfriend adore hanging out with the grandbaby but I'm actually furious and seriously butthurt by my daughter. So I won't be reaching out to her anytime soon, other than to offer babysitting.
It's the willful ignorance and disrespect toward myself that wilds me up.
I will be giving her the talking to, that I never had with her before, at some point. She is being quite spoilt princess-y.
The narcy tactics of her dad had me on the back foot for too many years. Given that I was 16 (and he 34) when I met him, and a homeless autist, I would say that my chronic experiences of powerlessness with the man, was pretty understandable.
He preferred to get in with smear tactic accusations first; didn't matter if they were wildly exaggerated, completely erroneous, or just exploiting my suffering, lack of social wiles and poor processing abilities. So, if I had tried to defend myself, it would just have come across as tit for tat and I didn't have any level of understanding of what was going on, at all. I really was convinced that what he said was true, that I was "crazy".
So, it seems my girl has imbibed a goodly amount of his narcissism toward me, I think very unconsciously, as is the way of these things, more often than not.
But she's far from being pathologically narcissistic.
Me and guy friend have modelled a lot of healthy relating, and she has expressed wanting "that". I think she has a lot of growing up to do though, and perhaps some "trauma recovery", however that looks for her, and I've said as much. Very diplomatically, I might add
One thing think she said, which, is kind of reasonable, from someone looking from the outside in, is that trauma can explain a lot of what she sees in my struggles, which is what the only psychiatrist I've seen said. Mind you, she was a trauma specialist psych, not an Autism psych.
I think what is underlying her attitude is the stance her dad always took. He had a favourite catch cry "labelling is disabling", and I think he has a terror of getting a diagnosis himself. No doubt he could cop some kind of cluster B diagnosis, and yet he does come across pretty Autie, as well. (You might be able to tell that I have an interest in clinical science).
I've had a psychologist who told me that he may well be psychopathic. So no doubt, my kids are gonna be pretty damaged, and maybe, probably, some of them struggle with empathy and compassion, both genetically and from our family culture
Actually, my youngest, the "gifted Aspie boy, told me " I would be a psychopath, if it wasn't for you, mum". He said he decided to be a kind person because of me and he's worked hard at it. I couldn't be happier with his progress. And he's only 18.
I think I want to tell my daughter. When you leave here, you will realize, I think, that nothing is more important that the kindness you embodied here. By many accounts; of those who experienced near death experiences, that had been what the "life review" is about, how kind and loving you were, and only that.
