Understanding these different dimensions—or what we can define as the "four stages or types" of betrayal—is essential for recognizing the problem and navigating the challenging path toward healing. 1. The Physical Affair (Sexual Infidelity)

Studies show men are often more distressed by this form of infidelity, often citing it as more intolerable, whereas women might struggle more with the emotional element. 2. The Emotional Affair (Emotional Infidelity)
