I completely underestimated how much my wife would want to talk about the details (one of my off-base assumptions) and that has been hard for me as it forces me to think about elements of the affair that I compartmentalized and that have been buried very deep for a long time. Seeing the trauma my infidelity is inflicting in real-time is beyond anything I could have imagined.
Think of it this way:
1st
It is a way your partner try to regain trust to you, seeing how honest your will be on things that will undoubtedly hurt her more.
Point is, and please be very careful not to lean into what I am telling you here, honesty is crucial: when a BS asks for detail there is a bit of dissonance.
You made mind movies that are far worse than the reality likely was.
You want to know the truth in part as a plea "please, I pray it is not as bad as I imagined it" hoping the truth will be less hurtful than what the mind does (and it does a number on you like nothing else when you are betrayed).
At the same time, you are scanning for lies, expecting that your wayward partner will minimize and try to paint it as "less than it was", so if you get a really tame confession about the details, you think this:
- My partner lies -> trust goes to zero
- My partner preferred the affair partner and is edulcorating the story to protect their real love and to hurt me less
When you get the truth, which is likely much harsher than the "hope it was not that bad", then you have to live with the answer.
Which means you will suffer another wound. But it does rebuild trust, at least a little bit.
We have a void where the life we have shared with our partner was kept hidden and compartmentalized from us. Confessing the details is sharing, even if in this case means gutting your BS again, you are allowing them again into your world, the very world where you cast them out to make space for the AP.
Not entirely sure if you can understand, but this is why she likely craves those details, why they hurt her, and why she needs it still. And above all why she does need the truth, and she will be checking over and over most likely, to ensure the version you told is real and not invented.
2nd
The trauma of infidelity is one of the deepest your soul can ever experience.
Imagine you enter in a communion with a person you trust the most in this world, you give them all your most intimate and vulnerable part of yourself, those secret parts nobody else in the world will ever see, to care and protect them. And they take yours and swear an oath to hold them safe, for the rest of their life.
That's a very deep psychological bond.
And the Wayward Partner not only fails to protect them from the outside world, they expose, mock and spit on them with the Affair Partner, who is a person that will gain self esteem by destroying every most intimate secret of the person who you swore to protect.
And it does not matter if you factually talked about and mocked your wife with the AP (as you probably did to some extent, is common), even if you never said a word, the actions you choose to take and the AP took with you did it, all her vulnerabilities, the treasure she entrusted you with, got tainted, spat upon and burned to ashes.
She gave you that believing you were the safest person to share her most intimate part of her soul. Now (at least) another person (the AP) soiled the most delicate part of your wife forever, with your indulgence in destroying it.
That's what will never be repaired, because it is done, you virtually "killed" her most delicate part of her identity. Once you killed it it will never come back.
That's why infidelity hurts more than losing loved ones.
It's a trauma of loss, ambiguous loss, because it is a loss that is not "addedd" to your life, it is "taken away", the void it leaves, is forever.
I believe you (any person really) will never be able to fully understand it unless you suffer it.
Whenever I heard about I could never figure how this truly feels. Sure is bad, but likely bad as many other awful things. When I suffered it I understood, it is worse.
Hoping you will never experience this, I tried to put it into words.
But words can't fully describe. Just imagine figuratively: my wife's AP. I would end him if I were to follow my instincts, in a way that would give nightmares to Dexter. With pleasure. However if I had the choice to make him go through what I went through, no I would not. Nobody, deserves to suffer through this.
