I'm ASD and ADHD and with someone who has both ADHD and CP. We actually have fairly similar narratives around midline crossing, processing, dyspraxia/motor type issues, bullying in school because of being gifted but also bullying in school because of being perceived as intellectually challenged, etc. The big difference between our presentation is that he outgrew his social awkwardness and I didn't outgrow as much of mine. I have social and speech/communication deficits related to my differences and he does not, I have shutdowns/I go mute sometimes and he doesn't, and I have narrow interests and he does not, and I have more sensory sensitivity and processing issues than he does, and I stim and he doesn't. Otherwise we actually have a lot of overlap in our presentation and we have more in common in our earlier experiences and challenges, than we don't.
I notice in my mixed-neuro social spaces (that is, every social space I'm in) that it's the extroverted ADHD people who act like the social "glue." The ADHD people who are most likely to be the organizers and risk takers and often leaders, the ADHD people who seem to be able to act as go-between between the autistic and neurotypical members of the space. My own partner certainly is the social "face" of our relationship.
We balance each other very well, but do not have the "long and intense conversation about 1 thing for 6 hours" energy. For that, I have my (autistic) best friend, who has some of the same interests as me.
