This sounds a lot like the way me and my wife used to be when we had little kids.
My wife is super capable, trained in childcare and very risk averse.
We used to argue about everything. I don't know you or your husband, so this is my analysis of my situation...
At work I was highly respected, a top employee, highly capable, used to being successful.
At home I was a failure. I couldn't do anything right. Any mistake or even perceived mistake and I was criticised in a way that made me feel a fool. Showing me my mistake, explaining in detail what I had done wrong. If I disagreed with my wife, then it would escalate. She would never see my point of view. I began to hate her. I would be scared to do anything, waiting for the inevitable criticism. I would avoid coming home, staying late to avoid being criticised. I hated it. I felt completely useless. A very difficult time. In the end I would argue about everything. I didn't want to concede on any point.
My wife probably hated me too. She probably complained I was always in a foul mood, and sensitive to any criticism.
I would not have appreciated a load of people online telling her to leave me.
I should have been less sensitive to criticism. I should have turned the other cheek and accepted my wife was stressed out with childcare, and only concerned for the safety of our kids.
I wish my wife had been able to realise how she was speaking to me, how useless she made me feel. It was the tone of voice. Hard to explain. I used to tell her that I would never respond to being spoken to like that. She would never accept that she was belittling me. In my head I dreamed of leaving probably every day. My love of my kids stopped me.
We're still married. Kids are teenagers and life is good (and just so much easier without little ones). We never fixed it. We just got through it. I'm sorry I don't have a solution. OP and husband don't strike me as currently being willing to take stock, reflect and compromise.
I'm not saying the OPs situation is the same as mine, I can't possibly know, but this is my experience anyway, and it feels similar.
