Because almost all of us were so blindsided by Discovery, we spend weeks, months, even years trying to piece together the "hows, whens and why's" of the deceptions generated by our chronic cheaters.
In attempting to create an orderly narrative out of the chaos that our mate's betrayals brought into our lives, we swing between trying to stabilize ourselves— and—trying to fathom how we missed their deceptions playing out right under our noses, usually for years.
Often, our sense of ourselves as formerly perceptive and/or intuitive can evaporate as we survey the breadth and depth of what are often incredibly elaborate deceptions unfolding in our relationship, unbeknownst to us.
