Back to the meeting with mediator for parenting, this could maybe be a good thing to eliminate some of the rubbish recently, although have to be on my guard that she won't start dictating and using it as a way to just have her way.
A mediator, unlike hashing things out in front of your kids, could be a great thing. My ex-girlfriend used a mediator with her ex-husband and the process was very smooth all via e-mail except the final signing. Note, their mediator made sure both parties saw all communications and was acting on both their behalves, never someone one party approached who would contact the other "in good course." That sounds more like her attorney. My ex-girlfriend also had a lawyer to check over any proposal she sent to mediation.
What issue do YOU feel you need a mediator for? I thought your Christmas situation was clear--unless she accepted your proposal in the app, you were doing a week on then a week off. I don't know how long you're giving her to make a decision. I think you originally said two days but didn't hear anymore about it.
