No viciousness -- calm, in command of your emotions, adult, firm. Does your W not earn as much as you? Or, not? If you have 50-50 child custody, and your W earns about the same, then surely you don't have to pay child support? I'm just throwing out thoughts here.
You don't have to lose the "Mr. Nice Guy" --- just be "Mr. Nice Steadfast Guy." The kids will gain from there being some stability --- that they know there will be no R, that this is the way things will be and they can move on from there.
Good to have the insider WAW friend.
Don't try and imagine what's going on in your W's head --- there is no controlling it, or manipulating it. Just do what you know is right for YOU!
