Good for you! You are not plan b! Great way of thinking. And I like the question Peace asked: what do you want? What if that happened? How would you feel? My favorite go to strategy is to 'Act As If'. Act as if what YOU want, is going to happen. Things will go your way. Be the best you. If you want W to feel loss, start separating more. Purge through your clutter, if you have any. Room by room.
Just your stuff. My spouses stuff is their stuff to sort out. It's kind of a contagious thing. Maybe W will see this and join in? See where this goes.

You Got This
