Curiousdan - he’s not having an affair - my DH (now Ex) started picking on me for everything - too much salt in the food, his shirts were not washed well enough , I didn’t dress well enough, our children were not dressed well , everything about me was wrong - you’ve guessed it -he was having an affair and finally, we divorced and he married. This was 20+ years ago. I’m not saying your DH is having an affair - (my Ex was much younger than your DH) - mind you I guess you can have affairs at any age . In this case, I think your DH is just grumpy 😂
