As I procrastinate from cleaning my desk, I'm struck once again how odd of a duck your H is.
Has he talked at all to you about this "new" person that he is? (forgive me, I'm not 100% up on your sitch at the moment). I mean, the man seems to want to talk. I don't know what the line between too much and not enough is, but you seem to be doing OK at trying to walk it.
If he's not told his parents, seems to me he's a bit ashamed/unsure of what he's doing, but that might be reading too much into things.
My best guess is to keep opening up to him, because that is new for you, but stop talking about the marriage. He knows you want to stay married, belaboring that point is as counterproductive for you as it is for me. He seems to want to know how you feel though, tell him if he asks.
One thought just struck me, it's like your H feels trapped/needed by you and that makes him want to run. Do your best to stop giving him that impression and stop the chase (yeah, ironic me giving anyone that advice, I know). Jui jitsu. Agree with him, to the extent that you can. He's set on working on this amicably. OK, fine. Work on the separation with him. You can either go with it or fight it. Fighting it is going to make him want to run further faster. Be fair to yourself, but give him what he wants. Keep taking care of yourself and making yourself more appealing. Make it hard for him to want to leave you.
I'm going to catch up on you in hte next few days and try to give you some real thoughts, but hope those will do for now
