When the Ground Shifts. Betrayal, Recovery, and the Long Work of Repair - Marcus N Tanner

When trust is shattered by betrayal, the pain reaches far beyond the relationship itself. It touches the body, the mind, the spirit, and the very ground a person stands on.

In When the Ground Shifts, Marcus N. Tanner, PhD, offers a compassionate, research-informed guide for betrayed spouses trying to find their footing after infidelity. Drawing from attachment theory, trauma research, relationship science, and the deeper resources of faith, this book helps readers understand betrayal not simply as a relationship problem but as a profound relational and emotional injury that requires honesty, safety, and time to heal.

With clarity and care, Tanner walks readers through the immediate shock of discovery, the chaos of intrusive thoughts and emotional flooding, the difficult questions of whether to stay, leave, or wait, and the long, uneven work of rebuilding trust and repair. He also explores what genuine healing requires, what true accountability looks like, and how to move forward with integrity whether the marriage is restored or not.

Written specifically for the betrayed spouse, this is not a book of shallow reassurance or quick fixes. It is a steady companion for those who need language for their pain, guidance for the road ahead, and hope that does not ask them to deny the truth.

If you are living in the aftermath of infidelity and wondering how to make sense of what has happened, When the Ground Shifts offers wisdom, validation, and a path toward healing on honest ground.
