What I've noticed is: At social events, everyone else mingles with ease, yet I'm lost.
It's like they have some instinct (or know some secret) that I don't.
Not quite an instinct, but this is the result of the general ASD characteristic deficit in the knowledge, skills, and experience needed for social interactions.
It's hard work and time consuming to address that deficit, but significant improvement is possible.
It's equally valid
not to address it of course, but then you have to accept the
status quo.
It has nothing to do with hurt feelings. All I'm doing is stating facts. Learning to be ok with rejection won't get my askouts accepted at a higher rate (so I fail to see the point of learning to cope with rejection)
I don't understand the quote above in the context of the OP. Note that I'm assuming that the person who said you need to learn to accept rejection is your therapist - i.e. that you were implicitly asking for input.
It's almost completely binary.
* If you "ask people out", you'll get rejected sometimes, perhaps almost always.
* You can reliably avoid being rejected by not asking, but with the obvious consequence.
What might you get if you ask a specialists? There's no straightforward answer to that, but here's a simplified and highly-polarized perspective:
If you force an answer from a "compulsively positive talk therapist" you'll be told "Just wait, and sooner or later it will work itself out". Which might feel nice in the moment, but it near-useless advice for almost everyone (NT and ND).
Or, if you're lucky enough to have a realistic therapist, they
should recommend things like:
* General self-improvement
* Work on your social skills, with a slight bias towards interaction with your preferred romantic target category/categories
* Acceptance of the inevitable negative side-effects of pursuing your objectives
It's always an option to "shop around" for someone who tells you what you want in the moment. Which is highly unlikely to lead to positive results, but if you're not going to follow a therapists' advice, you might as well select for feeling good while listening to it.
