((((Car)))) thank you for posting. It helps a lot to know others have experienced similar things in the world of weird and crazy-making family dynamics. I am working really hard right now on separating myself from them by No Contact (courtesy of DoNMs).
I could literally drop off the face of the planet right now and none of them would notice.
My mother was a master at triangulation and manipulation. I understand that now.
The only thing now that I feel I did "wrong" was to try to get them (for years and years and years) to see it and acknowledge it, too. But those were the enablers to the destructive behavior.
