This article explores the idea that relationships of attachment security are simultaneously relationships of mutual desire.

By recognizing that personal agency is vital to both healthy attachment and romantic desire, we can begin to appreciate the dawning of romantic desire, not so much as promoting “separation-individuation” as often conceived, but as exerting a gravitational pull to revisit an original love—one that is now erotically reconceived. We reclaim an original love but now in a relational context between mother and the Other, the pre-Oedipal and the Oedipal, the familiar and the stranger.
