Regular reminder that being an asshole is not a symptom of any form of neurodivergence. (You can replace “neurodivergent” with depressed, anxious, bipolar, etc. and the diagram works equally well)
ETA: social faux pas, awkwardness, and genuine symptoms of neurodivergence don’t make you an asshole. I shouldn’t have to say this? An “asshole” is someone who enacts a pattern of abusive, controlling, harassing, and/or harmful behavior with no remorse or concern for how other people are affected.
You aren’t being mean. Honestly it sounds like you went out of your way to be nice.
I just think that chances are there is note going on. It really isn’t on you and he may just dislike you as a person.
