Hi Achilles,
Given everything that has happened, and that you and your wife are in the MC process, it is a good time for you to take a step back and think about how much you may have compromised or turned a blind eye to during the marriage, and whether some of your accommodation of your wife's flaws inadvertently enabled them to continue unchallenged and unaddressed.
I think it is very good that you have accepted that you cannot fix your wife - as you once believed you could - and that only she can do that, providing she is actually capable of that (which remains to be seen).
As part of that, it would be good for you to step back and consider what you need to see - and it needs to be tangible actions - if you are going to continue the marriage. You need to get this clarity for yourself, and make it a non-negotiable checklist.
I also think it would be good for you and your wife to write out your definitions of love, what the word means, and how you believe it manifests itself. Both of you need to understand how close your interpretations of 'love' are, because if your wife believes she loved you while actively pursuing her affair, she clearly has an understanding of love that includes abusive behaviour like lies, betrayal, and sex with other people.
There have been discussions here about whether 'love' is a feeling/emotion, or an action.
Personally, I believe the two things are inseparable, and that a feeling/emotion that is not accompanied by supporting actions is basically worthless, and essentially meaningless. Your wife needs to investigate how she loved you while having her affair, because the two things are not compatible in any healthy interpretation of love.
I think your wife needs to demonstrate a commitment to who she wants to be as a person, as opposed to who she wants to appear to be.
In one of your early posts, you said that your wife was worried about people at her work finding out about her affair and thinking of her as the 'office whore'. In effect, she was far more concerned about people knowing about her actions than she was about actually committing those actions.
That is troubling.
It suggests that she believes that abuse and wrong-doing are fine in themselves as long as she does not get caught doing them. The principle of appearance mattering more than substance.
I might be reading too much into this, but I was struck by your wife's mother responding to your wife's confession about the affair by saying that her perfect baby was perfect no more (and the impact that had on your wife). It made me wonder if the origin of your wife separating appearance and substance in her life might have been her trying to appear 'perfect' to her Mom, while falling short of that in the reality of her life.
Is it possible that your wife's perfectionist mother left her with a sense of inadequacy about who she really is that has led her to (1) present a false facade to the world that does not match her reality, and (2) has made her dependent on external validation to an unhealthy degree, leaving her vulnerable to advances from blatant opportunists like her affair partner?
Those are things that she needs to work on in her IC, and she should keep you informed about her progress, because she needs to stop living a life based on appearance and reality being so different. They need to be the same thing, and that goes beyond the issue of infidelity.
Hopefully your wife will commit to making those changes, because both of you would benefit from them.
