With regard to human relationships, couples may expect sexual monogamy of each other. If so, then cheating commonly refers to forms of infidelity, particularly adultery[9].
Many people consider cheating to be any violation of the mutually agreed-upon rules or boundaries of a relationship, which may or may not include sexual monogamy. For example, in some polyamorous relationships, the concepts of commitment and fidelity do not necessarily hinge on complete sexual or emotional monogamy. Whether polyamorous or monogamous, the boundaries to which people agree vary widely, and sometimes these boundaries evolve within each relationship.
Infidelity is literally a breach of faith. Fidelity, derived from the Latin word for faithfullness, is the principle of not deceiving one capable of being deceived. Infidelity is a breach of good faith that applies in a number of other contexts (for example religious). In the context of this article about close relationships, infidelity is referred to as cheating, which is 'any violation of the mutually agreed-upon rules or boundaries of a relationship'. It does not require sexual behaviour to qualify as infidelity. The definition of what constitutes an act of infidelity varies between and within cultures. People in a close relationship may have very different ideas and perceptions of infidelity - see Blumstein. A man cheated by his wife is referred to as a Cuckold but no equivalent word exists for a woman cheated by her partner. The term describes a married man whose wife has sex with other men [1].
