What Is Infidelity?

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? Can you and should you forgive and move on?
