Good, CSCE. Do not let this go until you have reconciled the disparity.
A simple way to consider this situation is this:
We are what we do.
A lot of people do not like to consider this as truth. However, our choices ultimately define us.
As an example, I know several people who attend my church who consider themselves charitable, compassionate, and down-to-earth. Yet these same people would never consider volunteering in a food kitchen to feed the poor; the people are too dirty and it would be a headache. At the same time, they will give charitably to organizations that actually do the work.
Are they actually charitable, compassionate, and down-to-earth? I would argue they are charitable, but that they lack compassion and are not down-to-earth.
So they continue to lie to themselves in saying that they care about the homeless when they refuse to get in proximity to them.
You must do the same thing. Yes, you are an adulteress. However, with growth, you can transition from being a cheater to being someone who cheated.
How do you do this? You face it. Toxic shame is killing you right now, and will kill your chances for being a better, emotionally healthy person.
"When shame becomes toxic, it can ruin our lives. Everyone experiences shame at one time another. It’s an emotion with physical symptoms like any other that come and go, but when it’s severe, it can be extremely painful.
Strong feelings of shame stimulate the sympathetic nervous system, causing a fight/flight/freeze reaction. We feel exposed and want to hide or react with rage, while feeling profoundly alienated from others and good parts of ourselves. We may not be able to think or talk clearly and be consumed with self-loathing, which is made worse because we’re unable to be rid of ourselves."
I think you have had toxic shame before the affair. I think it is a large reason you sought the affair. It was an escape from that toxic shame...just like your previous addiction was also an escape...just like your next addiction when the shame starts to become overwhelming...unless you address it now.
Beating toxic shame begins with loving yourself. How do you begin loving yourself? By adhering to principles. These principles become the parameters of your life. They are simple things like always telling the truth with love no matter the consequences.
When you are faced with potentially detrimental choices, you fall back on your principles and values to make the right choice. This builds self love and self respect and in turn, makes it easier to make the right choice. It then becomes a positive feedback loop, as opposed to the toxic shame negative feedback loop of making a poor choice, hating yourself, making another poor choice, etc.
This is why one poor choice often leads to relapse in addicts, with the spiraling effect of the negative feedback loop.
CSCE, address your toxic shame and you will have gone a long way to making yourself a safe partner again.
Take care.
