Yeah, kids say the weirdest things. A few months ago, my W, the kids and I are coming back from a day of just hanging out together. We're in the car getting close to the house and one of the twins (he's 4) says: "I want mommy to sleep at daddy's house!" I guess he's feeling the goodbye coming... My W just sort of laughs and basically ignores it and then switches subjects. I think those kind of things basically just embarass the WAS, but it probably doesn't mean much else.
I do think that there has been a change in your W's behavior. And time will tell if her attitude really has changed. Keep doing what you're doing and be consistent. It seems to me that's probably the most important right now. You don't want to change your behavior right now and make her question herself again. Keep the positive interactions going for a bit.
