I totally get how you feel. Totally. I was so over the fighting as well. In fact I gave up on 20,000 in marital support cause I just didnt want to fight.
We need to protect ourselves financially and every time you do that, your STBX is right there basically calling you a B!tch because you are not agreeing with his every decision. Nothing you can do to change that. Continue to stand up for yourself and your kids finances but also remember its only money and sometimes it may not be worth the aggravation.
They have no choice but to make you into a monster that they tell themselves you are.
What are the financial consequences of the contempt hearing, how much could you win & what are your legal costs? Do a spread sheet for this.
Your STBX is a jerk and so is his dumba$$ girlfriend
