RADAR is a named, repeatable framework for relationship check-ins created by the team behind the Multiamory podcast. It gives partners an agenda to run on a regular schedule — monthly is a common cadence — so that maintaining the relationship is a normal habit rather than a reaction to crisis. The acronym structures the conversation: Review how things have gone since last time, Agree on what's working, Discuss issues and concerns, set Action points, and Reconnect with something positive that reaffirms the bond.

The framework caught on across the non-monogamy community because it solves a real problem: open conversations can sprawl, turn adversarial, or never happen at all. A shared structure keeps a check-in focused, makes sure concerns get raised before they fester, and ends on reconnection rather than a list of grievances. It works for monogamous couples too, but it's especially valued in polyamory, where more relationships mean more to track.

RADAR is one example of a broader move in modern relationship culture toward treating communication as a skill with teachable tools, rather than something you're supposed to just intuit.

Where this term fits in the wider picture

Ethical non-monogamy is a network of overlapping practices, identities, and structures — and RADAR connects to several of them. The neighbouring terms below show how this one sits alongside the rest of the vocabulary practitioners actually use; the guide at the end is the longer-form treatment of the same territory.

Closely-related vocabulary

Check-in
A regular, scheduled conversation where partners review how the relationship is going and surface concerns early — a cornerstone practice of healthy non-monogamy, since more relationships mean more to keep track of.
Agreement
An explicit, negotiated understanding between partners about how the relationship will operate — distinguished from rules in modern polyamory writing by being mutual rather than imposed.
Boundary
A statement about yourself — what you will or will not do in given circumstances — distinguished from a rule, which is a statement about what another person must do.
Jealousy
The felt sense of threat or loss triggered by a partner's connection with someone else. In ENM it's treated not as a verdict but as a signal to be examined — usually pointing at an unmet need or an underlying insecurity.
Consent
The freely-given, informed, ongoing agreement of everyone involved. Consent is the single feature that distinguishes ethical non-monogamy from cheating, and it must be specific, revocable, and uncoerced.

Questions practitioners actually ask about this

The longer treatment of this territory is in the guide Boundaries vs rules — and why the difference matters — Why most 'rules' between partners are really boundaries about yourself — and how confusing the two reliably undermines a polycule.
