KK: /ˈkʌkəldri/
The situation in which a man is married to a woman who has sexual relations with other men, often without his knowledge.
He felt humiliated by the cuckoldry that was happening in his marriage.
Cuckoldry → The word is derived from "cuckold" (from Old French *cucul*, meaning a male whose wife is unfaithful) and the suffix "-ry" (meaning a state or condition). Cuckoldry refers to the state of being a cuckold, or the condition of a man whose wife has been unfaithful.
Think of a man in a 'state' ('-ry') of being a 'cuckold' — a term for a husband whose wife is unfaithful.
