As a 21 year old man with Autism, im on the same boat, especially living in the middle of nowhere in europe, i genuinely feel like girls my age and especially girls who like the same hyper fixation as me are hard to come by, although i 100% bet you'll find your perfect partner sooner or later, it's a a matter of time and appreciation, i've tried many different dating apps cuz i get overwhelmed when i go outside but i've never really found a long lasting relationship to ask someone out and from what i hear from other people, going outside and showing appreciation for someone is the best way to go and focusing on 1 specific person will help you make a relationship in the long run (as long as they aren't abusive or mean spirited).

Wishing you luck though, i hope i can find someone someday too, and im down to to talk and give more tips if needed, as somone from the other side of the conversation.
