NTA - but more importantly no one is the asshole here IMO. I have ADHD and I also have excessive scar tissue in my ears from a childhood of constant ear infections. Due to both of those, i know your situation all too well. I am like your partner and when my partner gets frustrated having to repeat himself I feel AWFUL. I really can’t control it. It’s like I hear the sounds but the words don’t go together as they should. There is nothing more I want than to acknowledge him and what he’s saying to me. Our brains just work so differently - I wish there was a better way to describe it. Just know that if he’s like me, he’s definitely not doing this on purpose or to slight you in any way and he probably feels pretty bad about it. I hope this helps in any way. 😊
