It's not possible, so I don't like to think about it, but I'll entertain the idea. If a girl showed interest in me, I'd be cautious and pretend like I don't care. I'd immediately think about all the bad stuff in my life, how I'm a useless aspie NEET with no future, no real hobbies, interests, friends, social media, etc.
I have absolutely nothing to offer, so the only way this hypothetical situation could happen is if the girl in question didn't know anything about me. With this in mind I'd get scared and probably ignore her because what happens when she asks what I do for a living or if I have my own place? I have no social media either, no one knows me, and I don't know anyone.
You get the idea; it's just not something I like to think about.
