Emotional and physical affairs are one of the most challenging issues facing couples in committed, long term relationships. People cheat for many reasons, but the themes are always the same, which are unfulfilled needs and a failure to communicate about the fulfillment of those needs.
Understanding the factors that led to the affair does not excuse it nor take away the personal responsibility of the unfaithful. Understanding the causes of the affair will allow you to determine how to move forward and heal from the painful impact of infidelity.
Infidelity is like an earthquake that shakes the foundation of the relationship, and makes both the unfaithful and the betrayed question everything they thought to be true about themselves and their relationship. But, despite the pain, guilt, and shame caused by the betrayal, many couples are able to survive this devastating event and manage to rebuild their relationship to be even stronger than it was prior to the affair.
