First off, It is over and done, you can't change it now....

There seems to be issues that are valid from her. Things that are coming up that shine both of you in an unfavorable light.
Trust is the most fragile thing we have. We give it reluctantly, we accept it easily, and betray it frequently. Sometimes we know when we do, most times we don't. We often take for granted, but when it is broken, or gone.....It finds us again battered and bruised , seeking to find it, yet unwilling to give it.
In order to give trust, we must feel trusted.
The things that came up yesterday with that. It took the therapist and your wife to drag the truth out of you TWICE....
How can you expect that, if you don't give that ?
One of her issues is she doesn't feel safe at your home...
Keyloggers, Snooping....Would YOU feel safe there ?
Sparks....lying is lying, no matter how big, or how righteous one can get..
That is one of the reasons that exposing goes against what MWD teaches...
