Limerence

Limerence is a term coined by Dorothy Tennov in her 1979 book Love and Limerence. It describes a particular kind of intense romantic attachment: intrusive thinking about the limerent object, an acute desire for reciprocation, mood that rises and falls with perceived signals from the object, and an inability to focus on much else. Tennov treated it as a distinct phenomenon rather than as the early stage of love, partly because limerence frequently exists without much of a relationship to ground it.

The poly community more often uses the term NRE — new relationship energy — for the heady early-relationship state. The two are related but distinct: NRE is the normal early-mutual-relationship onset, often settling into a calmer attachment within months; limerence is the more pathologised, often unreciprocated obsessive attachment, harder to settle, sometimes lasting years.

Why the distinction matters in polyamorous practice. Treating limerence as if it were NRE — assuming it will pass on the same timeline, behaving as if the felt intensity is information about the relationship rather than information about your own emotional state — produces specific failure modes. A limerent attachment to someone outside an existing relationship can be devastating for the existing relationship if acted on as if it were a new mutual partnership of equal weight; a limerent attachment to a new partner inside an existing structure can mean the new relationship is being asked to bear more than it actually contains.

What helps when you suspect limerence rather than NRE: slow down. Don't make large structural decisions. Talk to a trusted friend or a therapist who can offer an outside perspective. Notice whether the obsessive quality persists when there is genuine reciprocation, or whether it specifically thrives on uncertainty — limerence often does the latter.
