ADHD husband nags me

My ADHD husband nags me. I do not have ADHD. He constantly repeats things, but that’s not always a problem although it’s annoying.

When I do something, then it’s a huge deal and instantaneous, before I can even explain to him what’s going on he’s already criticizing.

He acknowledges that he has to learn to “put on the emotional brakes”, but it drives me crazy. He can’t or won’t let me have time to myself to regroup if I get angry either, so it leads to me feeling like he’s poking the bear with a stick 100 times, then I get angrier and I eventually lose my temper.

Where do we start? He thinks he needs to see a psychiatrist and get medication.
