Is this a woman thing? Or a Pippa thing?
This is a neurodivergent thing combined with a "surrounded by unreasonable women-minds during formative years" thing.
Imagine how we know women to be, and then imagine how petty girls (children and teenagers) are in their peer relationships ("yeah she's not talking to me anymore, so I guess ___'s my new best friend now" etc). If you're burned by interpersonal relationships, an intelligent Asperger's or similar will seek to analyze the people and relationships around them to figure out what went wrong. Pippa, seeing these girls around her, would naturally come to the conclusion that friendships are transactional, by extrapolating the most characteristic (so she thinks) effects of interpersonal friendship that she can observe (such as so-and-so talking about why other girl is mean or didn't talk to me or is a bitch--typical girl shit).
And so, without having a friend who would stick up for her as a true bro would for another bro, and without consuming media which features this trope either (these are typically in coming-of-age stories which boys like, and she probably was never into that type of shit), we can easily imagine just what sort of "friendship" she was exposed to as a girl growing up around other girls, while being neurodivergent to boot.
I'm not a psychologist, but I believe my points stand on their own reason without an appeal to credentials. If she reads here, I would answer "how do I know what do people want in a friend" with "
assume their desires are the same as yours (if you believe your desires to be reasonable, others should hold similar desires, no?)
and if they take offense (assuming you are being honourable in your dealings with them--
genuinely betraying one's friends is indeed something to be ashamed of, and being distant does not constitute such a betrayal),
they are at best "adequate acquaintances" rather than worthy friends.
