Wow, great points. I think you may have something with the blind trust. Like you, I trusted so blindly that I think it allowed me to take too much for granted. Something to think about...
WP, in your case, I think a good transparency plan was called for, and I had suggested it. Did you guys ever do that?
My trust issues have more to do with me trusting my wife with my HEART again, moreso than me being worried about any repeat infidelity AT THE MOMENT (I do worry about it long-term). After a year and a half, I finally let go of the keylogger, and now she's suddenly chatting more on the computer all of a sudden.
