Hi Bahama,
I think that I may never be able to understand the why and how she was able to do this.
I think that can be a big element in the aftermath. Kind of like finding out that the nice old guy from down the street went into work one day and shot several people. It shakes our faith, and doubt our judgement.
The truth is that people are always more than we see, and that cuts both ways in terms of 'good' and 'bad'. It can leave us wondering if the person we married has been replaced by a sociopathic impostor.
Our disorientation stems from the way we put people on a pedestal when we love them, until we go through a experiences like this, which show us that our perfect angel or our knight in shining armour have feet of clay, and dysfunctional parts of their personalities.
Does that mean they cannot redeem themselves? No, because people are capable of both growth and change. Look at yourself; you are not the man you were at 18. Or at 25. We actually change every day, in ways so small that they are undetectable.
What happens with infidelity is that people demonstrate the dark side of their character. The weak spots. The holes in the fence. We all have them, and we all battle them. We all have our skeletons in the closet. In healthy personalities, that leads to learning, and a desire to not repeat behaviour that we regret or feel remorse about.
The point with holes in the fence is that in a healthy mind-set, we mend them when we find them. In an unhealthy mind-set, we climb through them.
And in my view, your wife was in an unhealthy mind-set when she gave herself the mental permission to cheat. The same kind of place where people are when they give themselves permission to rob a liquor store. They surrender to the conjoined twins that enable so much negative behavior in human beings: resentment and entitlement.
"I resent being broke, so I am entitled to rob the liquor store".
Resentment and entitlement. It really is a chicken and egg situation. Does a sense of entitlement lead to resentment, or does entitlement arise from resentment? However it happens, it is a totally negative process, and one that your wife fell into.
However, we have to stay grounded. Affairs happen when the affair partners are attracted to one another. If people are in a healthy mind-set, and they are committed to an 'exclusive' relationship, they can experience advances from many attractive people and not fall off the proverbial straight and narrow.
If people have already slipped into the resentment-entitlement cycle, where the two elements reinforce and fuel one another, they are much more susceptible to an inappropriate advance from a third party. The resulting affair actually validates both resentment and entitlement; "I am now getting the attention that I deserve, after being deprived of it. Why should I feel guilty about that?"
As betrayed spouses, we can come up with a million cast-iron rebuttals to that question, but as we grapple with the question of what messed-up alternate universe our wayward partners were inhabiting, we need to recognise the way dysfunctional thought processes work.
We also have to accept that our wayward spouses may well have focused and fed their resentment to enable themselves to cheat as (1) their right to 'appreciation', and (2) a way to get back at the target of their resentment, who they cast as a wrong-doer who is undeserving of loyalty.
This combination of factors is not behind every infidelity; however, it does seem that the self-reinforcing circle of resentment-entitlement was a big factor in your wife's decision-making process: "I am just a pay-check to you". So how much loyalty do you deserve?
Totally and utterly effed up. And yet...It happens every day, particularly when people do not give voice to their concerns.
Why do we keep so much to ourselves? Why did your wife not take you aside and tell you that she felt like she was being neglected when she came home? Why did she stay quiet, and allow that resentment to build, then respond to a selfish opportunist? Questions to put to her, and the answers will provide a project plan for change.
...we were there in this setting, but we were not really there. Both of us were lost in our thoughts about us and where to go from here.
Bahama, that is entirely natural. Please do not worry that this state is going to last. It passes. Normalisation takes time to arrive, and depends on a combination of time and proven commitment.
Before I go, I want co close on these thoughts:
Forgiveness is not endorsement.
We forgive people, not individual acts.
Forgiveness takes time; meaningful forgiveness cannot be rushed.
Forgiveness is not essential for reconciliation; acceptance is, coupled with a commitment to change by the wayward spouse.
