The key to healthy relationships that involve such ruptures is repair—repair, repair, repair. Repair is of central importance in healthy, secure attachments. Repair is an interactive process in which the rupture is recognized, reconnection is established, and attunement and resonance are experienced as a soothing process.
Siegel defines repair as the central, definitional process of secure attachment—an interactive restoration of attunement following rupture that enables relational continuity.
