How is infidelity defined in relationships?

• A. Emotional closeness with someone else
• B. Nonmonogamy with consent
• C. Instances of nonconsensual non-monogamy where a partner violates an agreement to be sexually exclusive.
• D. Revealing relationship issues to others

Answer: (C)

Infidelity is best understood as a breach of an agreed boundary of sexual exclusivity in a relationship. When a partner acts outside the rules the couple has set—whether sexual activity or, in some relationships, emotional closeness—that breach undermines trust and is labeled infidelity. The essential point is that it’s about violating a boundary the partners agreed to, not merely feeling attracted to someone else. If both partners explicitly consent to nonmonogamy, as in consensual ethical nonmonogamy, that isn’t infidelity because the boundary has not been crossed. Emotional closeness alone might not be infidelity in a relationship with different norms, but it can become one if it violates an agreed rule against such closeness. The other scenarios don’t fit because they describe situations where there is consent or where infidelity would depend on the specific boundaries set by the couple.
