If I may ask a related question, how important is neurotype compared to other things?
The double empathy problem is indeed a thing, but I wonder if it trumps other relationship needs.
Sure, you can both be autistic, but if you have no interests in common and just don't meet each other's relationship needs, then it likely isn't going to work.
And maybe it doesn't matter if two people don't share a neurotype if they understand each other and can work around each other's quirks. Supposedly there's a number of NT people that find info-dumping "cute".
