Some background about "JustPearlyThings".
She doesn't do dating advice as such, so you shouldn't expect guidance from her videos.
What she does is try to separate reality from fiction: show how some interactions between male and female humans actually work, rather than how people say they work or how they think it works.
This is a "triangle" that's troublesome for Aspies: the objective truth, subjective truth (what people (choose to) believe to be true), and what people say is true. In this particular domain that triangle is very large - the scale of the gap between facts and claims is startling.
I believe that she (Pearl Davis) is sincere, honest, and that her opinions are generally based on fact rather than fantasy or a delusional agenda. The presentation is generally lightweight, but it's YouTube (she has over 1 000 000 followers), TikTok etc. For these topics and audience, these mediums require a lightweight style, so she can't really be criticized for that.
But these are complicated times for people who prefer objective truth about human relations and relationships.
And JustPearlyThings covers topics that abound with people who do have agendas, and aren't inclined to base their opinions or utterances on facts.
Needless to say, she has haters as well as fans, and there are unbalanced people on both sides.
One comment on the content in the linked videos - just something to think about ...
Women rarely approach men IRL looking to start a conversion that might lead to some form of romantic contact.
When they do, it's usually one of the "lucky 10%", which includes very few male AS's in proportion to our numbers (now that Elon Musk isn't popular, perhaps nobody /lol).
This makes comments about rejection and related topics highly suspect.
The Hunter/Prey model is sexist. It survives because these interactions are not equal.
This is obvious, but the spirit the times requires that it's denied. Along with a lot of other objectively true things about human behavior, beliefs, and interactions.
Sadly, this is an "Aspie-unfriendly" phenomenon.
