Is it more than just miscommunication?

Sorry decided to delete.

A little of both...

"These issues I struggle with because I don't know if it comes from ADHD or he is just an asshole."

More than likely, it's a little both.  One tends to combine with the other to make things worse by multiples.  You'll find lots of examples on these boards.

The tricky thing is distinguishing between the two.

This, "Another huge issue is that I find him to be extremely judgmental of others, including me," for example, is probably mostly due to him acting like an asshole.

While this, "I try to talk to him about things rationally but he interrupts, doesn't listen, and will even respond with answers completely not focused on what we're talking about and I get exacerbated that he's not getting what I'm saying," could be related to ADHD.
