Go over in the newcomer section and read Littlebitlost's email to her husband. Read that as if that was your wife writing to you. Lilbit had her switch flipped and can see what she did and now wants it all back. Eventually it will happen with our respective spouses.
I think that this is the kind of awakening I'm hoping my W to have, but I wouldn't need to recieve such a long email. All I'd want W to do is to say sorry, or even acknowledge that shes done wrong. At the moment her attitude is what's done is done, I have no regrets, oh just get over it Lan (That hurts).
To answer another one of your points, I don't need closure now (it would help me) but we will need closure eventually if we are to sucessfully move on from all of this.
