Infidelity: Who Cheats, and Why?

Infidelity is breaking a promise to remain faithful to a sexual partner. That promise can take many forms, from marriage vows sanctified by the state to privately uttered verbal agreements between lovers. As unthinkable as the notion of breaking such bonds may be, infidelity is common—and when it does happen, it raises thorny and painful questions. Should you stay? Can trust be rebuilt?

Love is the most profound emotion known to human beings. For most people, romantic relationships are the most meaningful element in their lives. But the ability to have a healthy, loving relationship is not innate. Almost all of us have experienced a failed relationship, and most of us have to work consciously to master the skills necessary to make them flourish.
