You are always going to be autistic no matter what you do.
As someone who was diagnosed late and never considered the possibility that I was autistic - I literally copied NTs. You'll find a lot of women like me doing the exact same thing and still struggling. As you said, you're going to always be slightly off. You can deny and hide and learn all the tricks, but you're never going to be a NT. Your brain is wired differently than them.
I sound harsh because you're going to suffer more if you suppress yourself. You are lying to people. I mean, you don't need to tell every single person you are autistic, but if you never tell your spouse or someone close, it will hurt them. You're harming your body for the chance of ONE person to say "hi." Is that not extreme? That's never going to bring you happiness.
You don't need to be happy to be autistic, I think you just need to make peace with it.
