I think yes, leave him be. Let him figure it out but try to maybe flutter around in his head....meaning when you see him, be hot smell good. Be nice and supportive, ask how he's doing and really care about the answer. Avoid any more mentions of OW. That's falling apart I think and he's really wondering what the heck he's doing.
As I've been told often lately (and I love it) "You are the prize.....act like it."
