I agree that, for me at least, a lot of this has to do with personal isolation.
My partner is EXTREMELY social to the point that it looks like magic to me. The biggest difference I see from living with someone like this is that he contacts people EVERY DAY. He loves to talk to and meet new people and others respond to that. When he wants to do something, they are down with it. And if his friends don't respond, he does not take it as personal rejection because he is secure in his friendships.
I, on the other hand, find that kind of constant contact to be a lot of pressure and, frankly, exhausting. I am not a fan of talking just for the sake of it. What if I only want to talk to you every three months? I guarantee those moments together will be meaningful and special.
But that's not how the NT world works. If you only call up people when YOU want them, they will do the same to you - and that feels hollow.
I only learned I was aspie less than a year ago and am also struggling with how to develop meaningful relationships that I can also be comfortable with. I'll let you know how it goes.
