These aren't intimate, happy relationships. They move their so-called "friends" around like pieces on a chess board. Not only to make you question the abuse, not only to keep you silent, but so that if or when you do choose to speak up, they can place those frie- I mean pawns in front of them and say "how can I be an abuser if I have all these people who say I didn't abuse them?"
They may give the appearance of having a good life. But what kind of life is this? I've wrangled with this question for ages. Imagine how much time and mental energy is put into making sure your pieces are in the right place, that your people think what you need them to think of you.
And you know, I'd bet money they're more aware that everything could come crashing down than they'd ever let themselves show.
