Sorry to hear of your troubles. Other than another lawyer all I can do is offer advice.
Cool off and don’t fight. Bitter and contested divorces are for the Rich and Famous. Your ex-wife has been given the upper hand by the legal system many many years ago.
I was slapped with similar TROs at the onset of my divorce. It was all lawyer language of “possible threat”, “possible violence”, “possible abuse”, but I convinced my ex-wife to voluntarily change the language.
You can probably ask for and compel family counseling (even if divorced) and try and work it out there.
BE PASSIVE AGGRESSIVE on all issues. You will lose if you have no money and try and confront her head-on. If you establish a record with the court of behaving, not making waves .. you will prevail over time.
And remember this: “The best revenge is to live a long and happy life”.
You are engaged in a legal system created by feminists for women and against men.
I can't offer you legal aide but I will pray for you. There is one Power in your universe that trumps them all. It is less human and warlike and more vulnerable, steady and patient. But it is immensely more powerful. It's spirit swallows up and nullifies the power of evil. Pray for healing, protection and deliverance. Pray for your children and let Him be their Father while you walk this plank of hell. He's really rich (owns everything and everyone) and He's super wise and just.
Since Americans no longer respect truth and honor, we need to make it more risky for liars (shake down artist false accusers) to operate in the court system.
You are like a football team that has lost a quarter. You can't replay it; the game is rigged up to this point. Her unjust legal power feeds on your sense of powerlessness, fear, outrage and anger and that state is where you are the weakest opponent. So get above this and out of this state as soon as possible - like now! When your energy changes from resistance and war, hers will change, too.
You need to be a patient, good and wise deal maker now. You are negotiating for an honorable deal for her, yourself and your children. You need the Holy Spirit to be your counselor and healer. Pray to Jesus and get a strong Christian friend to talk with who can support your spiritual growth and power in this.
