Edward, as much as this time and your W's words and actions are frustrating for you, that is all outside your control.
If your W does continue to proceed with this mediator, or gets a different one or a therapist... those are all things that she will or will not do, on her own time and initiative, IF it is what she wants.
I believe it will serve you much better to work on letting all that go and let it play out as it will. In the mean time, focus on yourself and moving yourself forward. There are positives in your life and those are the things that you need to focus on.
Aside from your job prospects, what else is going on in your life that you are happy for?
