Well, yes.
It’s like waking up in Alice in Wonderland, isn’t it? Without the fun bits

Help, I think you are going to have to start working harder to tell yourself that her opinion does not matter. Or not to you. Not of how you parent, not of how you reply to a factual question, not of what she thinks about you or the price of cheese. Stop apologising, stop taking the bait, stop listening to her opinions. Try to see that she is manipulating and weoponising these simple interactions and that normal decent people don’t do that. Learn to shrug and walk away. Find a word in your head to use that helps you do that….Whatever, Meh, Blah blah, not my problem. Use silence, don’t chase the ball. (And be very aware of any agenda she might have about claiming you are a poor parent….take legal guidance on this, document the necessary things, let your kids speak for themselves rather than letting your wife tell you what they think, be aware of ways in which you might inadvertently be using your kids as either a temporary comfort blanket or a connection to your wife)
On a practical note, where are you in the legal process? How much longer until you are no longer living under the same roof? What arrangements are in place for you to spend time with your kids right now without her being around?
