I agree with everyone. This is your opportunity to put it out there when he says he is ready and your want to make sure you make it crystal clear what you expect to happen. I know some people suggest you also ask to see a final letter/email from H to OW stating that he has choosen to work on M and can no longer communicate. Don't know if you want to go that route, but it might be a good way to know it has happened since he has said in the past they weren't communicating and they were.
