Limerence is the all-consuming, intrusive-thought stage of infatuation — distinct from love in that it's driven by uncertainty and the hunger for reciprocation rather than steady attachment. It typically fades over months. The concept matters for AI companions because the always-available, always-affirming nature of an AI can sustain a limerence-like loop longer than a human relationship would, since the uncertainty never fully resolves or breaks. Recognizing limerence for what it is — a brain state, not a verdict on the relationship — is one of the more useful pieces of self-awareness for anyone in this space.
