In a sense, this book is intended for all married people. Knowing the essence of fallen human nature, we understand that infidelity poses a danger to absolutely each of us. But first of all, the book is written for those who have already been affected by infidelity, whose marriage is facing such a threat at the moment, as well as for those whose marriage has already broken up. For those who have divorced or left their family, the book will help them understand what happened in their marriage. It will also be useful to those who, as a professional counselor or just a close friend, are trying to help those affected by this disaster.
