Ethical non-monogamy

Also known as enmconsensual non-monogamyopen relationshippolyamory

Ethical non-monogamy is any relationship style where partners consensually and openly engage with more than one person — grounded in honesty, agreement, and clear boundaries.

The gist

Ethical non-monogamy (ENM) is an umbrella for relationship structures — open relationships, polyamory, and more — in which everyone involved knows about and agrees to the arrangement. The 'ethical' part is the point: it runs on honesty, communication, negotiated boundaries, and respect, distinguishing it clearly from cheating.
