Autism is not a deal-breaker. My spouse has ADHD and I have ASD. Granted, each of our neurotypes causes the other some frustration, but both are also factors in why we were attracted to each other in the first place.

Neurodivergent individuals often select for each other in partners and there are a lot of similar patterns in my extended family (to use your phrasing, they're all a bit "off"!). None of the relationship failures have been as a result of neurotype and most are still married, with the failures due to the same problems that NT couples deal with - poor communication, emotional immaturity, refusal to learn and grow, etc.

The key thing is to be yourself. If she likes you, you want her to like you for you, not the facade that so many of us have to wear to survive in the NT world.

And if she ghosts you, that's not a failure on your part. It says more about her than you - you took the risk and put yourself out there. If she doesn't show, perhaps she is insecure and afraid of telling you she's changed her mind, or perhaps something happened to prevent her from being there (since you mention films, this is a common trope too). Just be kind to yourself.
