Don't push for it, you really have to let him come to you or you will chase him away. You will know when OW is gone because H's behavior will change, as will his communication and attitude. He'll then go through a period of grieving during which he might act even worse. You'll know, but you have to let it happen on his timeline and not yours which is hard I know.

Don't contact him, don't initiate anything. Just wait, he will eventually reach out to you, but you have to wait for it.
