I'm so sorry and get it.
Remember to stay very calm at the hearing, no matter what. Stick with the facts, be genuine and don't editorialize. You want to show the judge you are honest and in total control of your emotions.
Hopefully you've documented everything thoroughly. Take notes during your STBX's testimony. Calmly point out inconsistencies to your L if your Ex contradicts herself.
Judges know people use RO's to gain unfair advantages in divorces all the time and they prefer not to issue them unless it's really necessary.
The bottom line is to show the judge there's no need for one against you because you respect boundaries and care about everybody's well being. You want everyone to move forward with their lives peacefully and amicably.
I know you have an L, but the judge may ask you questions. Show him you're on the high road. Be sure to wear your best collected and sincere face for this one and it'll be ok.
