Aside from me going full on psychopath and following her around or hiring a PI, I have no intel. I don't think I want to live that way.
What "way?" Knowing the truth, so that you can act accordingly? How are her current clouds of deceit serving you?
For the LIFE of me I don't understand why so many on these forums want to be WILLFULLY in the dark. You're flying the jumbo jet of your marriage and family through storms and rains, and you're ignorantly turning off your instruments.
