There is a recent topic over in General called "Conundrum: good person/bad acts or bad person?" which I think might be helpful to read as well in relation to this. In that thread, I posted the following (I hope this is okay to post, I'm not always sure what the cross-posting rules are)...
If I may add one other thing because I think it is important, that label of being a "good/bad" person really did seem to trip me up for the longest time. Labeling myself as a "bad person" in some ways only inspired me to "live up to" that definition, and felt like a cage that I was trapped in. I was so busy trying to decide if I was good or bad or whatever that it completely obscured the fact that my wife was continuing to suffer. Labeling myself as a "bad person" only made me more desperate and needy, and dependent on others to validate me, and I was so busy hustling for my own worth and trying to make my wife happy (in order to make myself feel better) that I could not see or hear her pain whatsoever over the noise of my own desperation in my head. That is the "shame spiral" that we talk about so much, and in many ways I feel it worse than the state of mind I was in during the affair. The only way out of that spiral (that I know of) is to accept who we are, what we did and why we did it, on its face value, and in order to do that, we first have to be "safe" for ourselves, which means not needing others to validate us. For me, I had to accept that who I am is defined by my actions and motives, and that I could regret the things I did and yet still find self-worth and hope within myself. The moment that switch flipped within my head, the "noise" stopped, the need to hustle for my own worth stopped, and my ability to empathize with my wife came back. The shame went away and with it went the defensiveness and need for self-protection. My remorse no longer manifests as shame, rather, it propels me to better understand my wife's feelings and experiences and fears. Is that good or bad? I still can't answer that. But it is rooted in reality, and in empathy, and in a desire to be a better person today than I was yesterday.
I'd also like to share this quote on shame from Brene Brown:
I define shame as the intensely painful feeling or experience of believing that we are flawed and therefore unworthy of love and belonging – something we’ve experienced, done, or failed to do makes us unworthy of connection.
I don’t believe shame is helpful or productive. In fact, I think shame is much more likely to be the source of destructive, hurtful behavior than the solution or cure. I think the fear of disconnection can make us dangerous.
Understanding the source of your shame is paramount. For me, what I needed to ultimately understand was that my feelings of shame went much deeper and farther back than the affair itself, and that my shame from the affair was simply added on to that, like putting a layer of shame-icing on a giant shame-cake. Scraping the icing off doesn't remove the shame, it only exposes the larger and deeper cake hidden underneath. I think that's why so many WS's get so stuck on this process. We keep trying to deal with the shame on a topical level, when in fact it runs much deeper.
I strongly recommend exploring the source of your shame with your IC if it all possible. It was a "light bulb" moment for me.
In order to give you an idea of what I mean, my IC and I did an EMDR session where she kept encouraging me to go back and think of my earliest memories of feeling shame. For me, that was a time when I was very young, in pre-school, and had accidentally peed in my pants during class. The teacher had to call my mother to bring in a dry set of clothes. When my mother arrived, instead of telling me that it was okay, and that things like this happen to everyone, she instead made a joke of it with the teacher, and the two of them laughed about it in front of me and all of the other kids, and that mortified me. Instead of helping me to build up my self-confidence, it instead tore it down entirely, and I learned that doing anything incorrectly was a reason to feel devalued and ashamed. I never learned how to overcome the shame or deal with feelings of guilt. What I learned instead was that my value was based on how others perceived me. When my mother and teacher, the people who were supposed love, protect and guide me, showed me that I was a joke to them for not doing things correctly, that concept stuck with me throughout life. I never learned to value myself for myself, I only learned to gain my value through others. There is more to it of course, but that one little act opened the door to years of abuse from bullies and others. Each time I was teased or bullied by others, my own self-worth went away, and my ability to feel good about myself, for myself, disappeared.
Fast forward 50 years, our marriage (like all marriages at some point) hit a rough patch, and suddenly, my sole source of attention and value, my wife, was not available to make me feel special and valued. It was what ultimately led to the affair. (I'm not saying it was my wife's fault, I'm just describing the conditions which triggered me to revert so deeply into shame and desperation). Like that little boy with piss in his pants, I just wanted someone to comfort me and tell me that I was worthy of love and attention at the level that I needed it. When the AP approached me and began to flirt with me, it was like finding an oasis in the desert. I jumped in head-first, all the while blaming my wife for pulling away from me, when in truth, it was me that pulled away from her. I just couldn't accept that, and had no emotional tools to deal with it.
Anyway, my point is, the way out of the shame spiral, in my experience (YMMV), was to go back to that point in time, to that little boy with the wet pants, and to understand what happened there, and to do what my mother did not. I needed to teach myself, to implant a new message, that my worth was not tied to my failures and mistakes and poor choices, rather, my worth was inherent, and determined by me and by who I choose to be every single day. I needed to understand that I could do something that I was not at all proud of, and yet not be forced to define myself by that parameter alone. Once I was able to change that one thought process in my head, all the other pieces started to fall into place like dominoes. The shame bubble popped, and with it, so too did the fog.
Imagine that your house is on fire, but you are asleep. What can you do about the fire? Nothing, not as long as you are asleep, you and everyone around you just burn up. That is what the shame spiral is like. Now imagine waking up and seeing that the house is on fire. Now what can you do about it? Suddenly, the possibilities are endless, and you can call 911, get people out, save your precious items, grab a hose, and so on. You can help to deal with the fire. That's what it feels like emotionally. It feels like waking up and suddenly understanding, organically, what is needed and what is important to deal with. That is when you can begin to help give your spouse what they need in order to help them heal, and to enable any chance of R.
