I don't agree with the numbers. I do agree with the message.
I think transparency is vital, on both sides, during this process, and it is a process.
I believe this to be 100% true in my case.
Here is the potential problem that I see in your case though...
She doesn't think (outloud, to you) that she did anything wrong.
However since you guys are talking, does she understand that while she doesn't feel that way, that you do? And because of that transparency on her part will help your (both) relationship heal?
If she doesn't...I don't see her agreeing to or being ok with the idea of 'allowed/expected snooping' as it were.
