It was really interesting to read the thread; and OP, I am very sorry about your childhood. It seems you are in a better place now! Some post-thread reflections;
-of course, consent is key, but the idea that no one owes anyone anything is ridiculous. Humans live in societies and owe everything to each other. To imagine that we are atomistic individuals, all self-sufficient and self-reliant, who can be "fixed" by specialists if things go wrong is just a misunderstanding of the history of humanity.
-there is a lot of cultural habit here, stiff upper lip (I am saying this as a foreigner). Talking about your feelings and problems, even non-trauma-related, is still v v difficult for many English people (that I know)
-and last, I had a similar experience to you, OP. Trying to make a friend, it didn't go quite well, she found me too intense. And yes, I was intense, I was in a very difficult period of my life, objectively hard and nothing to do with my own childhood. We are still superficial friends, but we will never be deep friends, like I am with a good group of other people, because she has had a very sheltered life, is naive, and entitled (of the kind that her pearls are too small). Not that I bond with other people with trauma (I don't think), but the complexity of life experience seems to define ability to imagine other person's life and empathise which is key to friendship.
I wonder what kind of person your new friend, OP, turns out to be. It is a very specific and interesting thing you met on which marks her as someone trying to think about life in a profound and meaningful way
