Hello,
I wonder if there’s something under the surface that is worrying your wife, or causing stress in your family? I ask because clearly she wasn’t this critical at the beginning, or you would never have married her!
Last year, our son was became ill with a psychiatric problem. Our world fell apart and sometimes, I would catch myself criticising my husband and wouldn’t believe the things I said, nor the tone of voice I said them in! I was just shrewing him night and day! After a while, I realised that I was ‘picking’ at things, trying to find some semblance of control in our family when everything else was falling apart as we struggled to help our son.
In desperation, and not wanting to add marriage counselling to the never-ending list of appointment we were keeping; I listened to Dr. Kevin Leman’s ‘Have a new You/Kid/Spouse’ audiobooks and bought a book; ‘Thriving Marriages’ by John Yzaguirre. I cherry picked the parts that were useful and paid more attention to my marriage. It wasn’t quick or easy but things came right in the end.
It’s hard when you find yourself in opposite corners, and harder yet when romance becomes routine or fraught with undercurrents of resentment, resignation or reluctance. It’s hard when your best friend seems to be on a different trajectory to you. It’s a deeply sad and lonely place to be.
I’m sure you’re bewildered; my Hubster surely was! We girls can be enigmatic.

Perhaps you both work hard but forget to play, too? Perhaps you’re all about the household and not so much about each other? Perhaps she hasn’t the first idea what’s prickling her? Only you, in your heart of hearts know how things stand.
I’ll say a prayer to St. Valentine that you get to the bottom of what’s causing this ‘picking’ and can set it right.
