My gut instinct after reading DB is to just remain cool and calm and act indifferent but kind.
SadDad8,
I think what you said is a good approach. In addition, and I'm not kidding about this, before you talk with your wife, see if you can find some boxes that she can use to pack her stuff and give them to her. It's kind-of a 180; you're showing her that you're ready to let her go.
"Boxes and tape" is a doodlerism (don't google that word just yet), but others may think it's a tad extreme. I like the gift of boxes because it makes a big statement without being mean and nasty; you're doing something to help the WW toward her goal.
