Wait - your daughter lives in TOWN and you haven't told her about all this? That hardly seems fair - what happens when she sees him in town with the OW in his car, or one of her friends tells her about the woman she saw kissing her dad at a restaurant?
Your H needs to man up and tell her now. It's not fair to let her find out one of those other ways. And she's gonna be mad at YOU for hiding it.
