At this point, I wouldn't sweat it. Premature at best. You can communicate a lot non-verbally.
Trust me, he knows how you feel about OW.
It's a small step; him solving his own issues with the kids, and actually showing some concern for your cute little ears, but it's a baby step.
However, since he's not really trying to get close, he's not crossing a boundary. IF he does, then it's time to say: "Back off until OW is gone. Then we can talk about it."
Nice as pie, of course.
Right now you're just being a cool chick with no expectations.
