I am a bit uncomfortable outling her steps in detail for her. They are on her site.
I woudln't call it WAS.
First, there are clear boundaries set. Children go WITH you, you don't leave THEM behind. There are clear terms for returning. It is lastly made clear that the detachment is to SAVE the marrige, not to discard it like an old shoe. There is every intent on returning to the home when the affair is over.
Not walking away, its TAKING AWAY yourself from the painful drama until its OVER.
