Okay - first - stop thinking about H and OW. He has told you it's over. It's actually pretty amazing that he seems to be showing actual remorse - do you think it's genuine? You can always get a new mattress later, new linens, paint the room, move the furniture around so it looks different, whatever. That's not quite as important right now.
Second - I would make another appointment with Chuck ASAP.
Third - if for some reason H brings this up again before you can talk to Chuck, I would say something like "I just wanted to say that I thought it was really brave of you to come forward like you did and admit what happened and be honest with me. Honesty is really important to me and is something I need in a relationship. I appreciate that you told me. I need a little more time to process what you said so that I can give you an honest response." Or something like that (making this up on the fly). At least until you can talk to Chuck and figure out what's best for you.
