I would replace thoughts of the AP with how wonderful my wife was for giving me another chance. I would remind myself that I was being totally selfish for having an affair on my family.
I worked on hobbies. I invested more time in the family.
Thoughts of the AP will come to your mind especially now that you have just recently started NC. That you may not be able to control. You can control what you do with those thoughts and that's dismissing them and concentrating on your family.
For the record...there is never a "right time" to confess. It just has to be done.
There are tragic situations that occur that could stall you confessing, but if you're doing it because "you're not ready"
Then you are still being selfish about this and protecting you and your AP.
I know it's a struggle..I've been there. But I would not be where I am today if I did not face and fess up to what I did
