The images and thoughts get better with time. Not sure about the betrayal itself. I certainly hope so. But it tears at the very fabric a marriage is built on and destroys the basic assumptions you have of your partner: that they will respect you, honor their vows, not lie, and not stray.
I'm struggling with patience as well. I think men naturally want to fix things and come up with solutions. It's a frustrating thing to know you need to sit back and let the situation ride out on its own. As a fellow accused controller, it's a delicate balance of not being pushy while also being strong and assertive so you're respected.
