You sound good. Just keep a positive attitude. If it doesn't happen with your wife then you did what you could. If I were you, I'd tell your wife the truth.
I would frame it this way though: "I know it probably doesn't change anything with us, except to make it worse, but I need to have a fresh start at life and do things right from this point forward." And then tell her what you haven't.
