It’s not a burden to date/hang with/be friends with an introvert. If you act like someone being shy and quiet and not as easily communicable as you is somehow a personal burden to you then you are an asshole, that will be all.
I mean it can be though? Like speaking as someone who has social anxiety but is trying to become more comfortable around strangers I know theres alot of people who don’t want to hang out with me because I’m really awkward/quiet at first, and that’s okay in the same way an introvert might not want to be friends with someone whose loud and abrasive because it makes them uncomfortable. Just because people have different wants and needs doesn’t make them bad people at all just not compatible.
There is a difference between your actions and your existence. And one of them tends to stigmatise a lot of neurodivergant people who’s conditions are viewed as inherently antisocial.
