This IS about you as a man. A man under siege. A man being tested.

I am off on vacation with my kids starting tomorrow for a week. I only say that b/c that is what you are fighting for. YOU get to decide about vacation. YOU get to do what YOU want. YOU get the one on one time. She is not part of the equation - no second guessing - no court - all guaranteed by law.
THAT is what you are fighting for. THAT is why you must stay the course.
