The issues raised by infidelity are complex and certainly there is no “cure.” Some people believe that infidelity is hardwired into our DNA, an urge passed down by ancestors who sought to disseminate their genes to future generations. Others say that it’s a moral failing that deserves the strictest punishment, such as certain religions that will punish infidelity with death.

Infidelity can be defined as, “the action or state of being unfaithful to a spouse or other sexual partner”;1 “the act of having a romantic or sexual relationship with someone other than one’s husband, wife or partner.”2

But no simple definition can explain the emotional damage that can occur when a supposedly committed partner cheats, and no one definition can answer questions like: Why do people cheat? Is an ‘emotional affair’ really cheating? Are certain people prone to cheating? My partner had an affair: should I leave?

The following articles should show what others think about this difficult and often hurtful issue.

I used to reserve the term only for relationships that passed the boundary into sexual intercourse, but that changed after watching a Ted Talk by affair expert Esther Perel called ‘Rethinking Infidelity: A Talk for Anyone Who Has Ever Loved.’
    ‘Infidelity,’ she explains, ‘includes one or more of these three constitutive elements: secrecy, sexual alchemy, and emotional involvement.’ Perel expounds on the three elements in her bestselling book, The State of Affairs.”
