"Please listen to this. My WW has been the perfect Stepford wife since about a year after D-DAY (Funny side note: many here on SI tagged my WW's behaviors as "Stepford wife" and this week I was talking to a friend of mine and he immediately described my WW as "Stepford wife" without any prompting).
But while my WW has done everything to show me the kind of wife she intends to be going forward, she has also done just about everything a WW could do to avoid transparency about her affair. She destroyed the texts, destroyed physical evidence, refused to write down a timeline for three years and refused to do a polygraph until I made it an ultimatum (a polygraph which she then promptly failed).
So how do you think the Stepford wife routine is working out for her and for me? Oh sure, I enjoy having my whims catered to, an espresso brought to me in bed every morning, being showered with gifts and attention consistently, constant physical affection, sex on tap whenever/wherever/however I want it, all household tasks being done by her. Sure, I enjoy that. Of course I do.
Who wouldn't? But do you need the answer beyond this? Do you think it has fixed anything, really, fundamentally?
This shit does not go away."

I'm going to guess that the missing pieces are the trust, compassion and companionship which are impossible for an unrepentant spouse to create without the genuine and consistent effort. It's as though she says to herself, "this is adequate enough to placate him."
What your W is doing is nothing more than what could be purchased from some kind of commercial enterprise/worker and thus lacks the substance needed for a real connection. Quite frankly it's less expensive to pay for said services on a one-by-one basis than it is to be married and this be the "arrangement".
The only fix is the one she refuses to move towards; complete transparency.
Just my anecdotal .02.
