ok. Is that somehow supposed to mean that YOU are supposed to do it, this time? If so, why?

Do you want to get D? If so, then set up mediation or file D. If not, then the onus is still on her to work through this. You are just along for the ride, doing what you need to do, within the time that you are supposed to do it, in the event that she moves forward.

Otherwise, what are you doing, to make yourself a man that only a fool would leave?
