This0is0Fine,
Leaving aside the debate that could rage about the nature of your wife's 'self' and the improvement it could use, what solutions has she offered to repair the damage she has done?
One person cannot fix a marriage, no matter how hard they work, but a lot of betrayed spouses attempt to do that exact thing. So has your wife suggested any plan for how to improve things, or does she just think carrying on as if nothing happened is the way to handle things?
No our marriage was not fundamentally broken before the affair...it is really a "crime of opportunity" type affair that occurred as a slippery slope of bonding over trauma she didn't feel comfortable sharing with me (she hadn't talked about her mother's death still affecting her to me for months, and had a big breakdown in front of him when they were on travel).
That offers some interesting insight about the different ways you and your wife perceived the marriage. For you, it was all fine, no problems, rolling along nicely. And yet your wife isolated herself and did not talk to you about a problem that was affecting her for months.
Have you discussed why she isolated herself and did not feel comfortable confiding in you? Logically, the person most adults would turn to would be the people they are close to; either their spouse/partner, or a good friend.
Do you think your wife is emotionally repressed or a person who lives behind a facade? And is she having any individual counseling? It sounds like both of you are financially solvent enough for her to be doing that, and she really needs to be digging deeply into who she thinks she is, what gives her validation as a person, why her mother's death is still so unresolved for her, and why she did not share that with you.
These two statements are intriguing:
A lot of it is driven by fear of change, her mother's death by suicide after a divorce with her father (because her mother felt no worth outside the marriage).
Aside from the "losing part of herself" reasoning is she was brought in as the first back office person on a total team of 13 and now is running a back office of ten or so people on a team of over 80. She feels like she is building something of value and doesn't want to quit before they finish this rapid growth period.
So your wife's mother killed herself because she felt no self-worth outside of her marriage, and your wife is prioritizing the 'something of value' in her job that makes her feel a sense of self-worth outside of the marriage. There is a kind of logic to that, isn't there?
Given the fact that her mother made her marriage more important than herself and her continued life, is it possible that your wife is trying to protect herself from the same thing by making herself - and her 'self' - more important than the marriage, and finding validation and self-worth in something unrelated to the marriage?
I think the two of you should discuss that, because her mother's death had a big impact on her, and the circumstances of it may be controlling your wife's thinking in relation to her own marriage and how important it should be to her.
In essence, is her mind-set "I am not going to make the marriage more important than me, because my mother did that, and it killed her"?
Ask her if she sees destroying the marriage as a way to save or protect herself as an individual.
Now, none of that justifies her affair, but for both of you I think it is definitely worth investigating whether the reason for her mother's suicide fundamentally changed your wife's attitude to the marriage, and gave her negative feelings about it, which might be why she did not discuss those feelings and issues with you. See what she says.
Edited to add:
A salient question to ask would be this:
Are you deliberately trying to destroy the marriage so that you can prove to yourself that you can survive without it?
I can see why many people think the business of preserving her 'self' sounds like utter bullshit, but your mother-in-law's suicide may well have made survival in and out of a marriage an existential matter for your wife.
Perhaps another question to ask is whether the suicide made your wife feel like she had no identity outside of the marriage, just like her mother felt.
