You never grow out of autism. You are always autistic, but you get better at compensating for it. In theory anyway. I've met ridiculous numbers of autistics who use it as a "Get out of jail free" card. Instead of, "I fucked up and did wrong by you, but please understand that I'm a social exceptional individual and while I do what I can I'll never be good at it" You get, "Baaaaawwww! I'm not to blame for anything! It's all your fault for not being supportive! When you said XXX it's your fault for not explaining it to me properly, even though you were saying it for months and months before this and I kept saying that I understood! Baaaaawww! You're so meeeean!"
The problem with the first option is that anyone has good days and bad, or NTs giving you shit for not 'trying hard enough' because they can't tell the difference between a human suit and genuine social ability. The problem with the second is that those shits spoil everything for everyone, especially their own biggest advocates, and whine when what they think is owed them turns out to be conditional.
