Damn legal system. There MUST be a reason why the judge thinks you two will "work it out".
I can say ignore the texts until my face turns blue - we all know its never that easy.
But do keep a record. I know there is ways to pull texts off a phone - but it takes an IT person to do that. Lexie is right - take screenshots that show the time and date stamp. All you can do at this point is ignore and document.
Can your court advocate also be present at any kid pickups/dropoffs? Or someone who can act as a witness?
