One thing that stands out to me is the fact that he says "the pain you are in" and not the "pain I have caused you".
Yep -- that's very insightful of you, Autumn. I call it "The 4 Stages of Remorse," and it goes something like this:
They'll go from "I'm sorry I got caught," to "I'm sorry for ME that I've messed myself up so much," to "I'm sorry for YOU that I hurt you (but I still don't see anything wrong with what I did)," to finally a more self-aware "I'm sorry for what I did because IT WAS THE WRONG THING TO DO, on so many levels. For me, for the pain I caused my wife and kids, for the breaking of my vows, etc."
I would peg your husband somewhere between the first and second stages right now.
