In the book "Housekeeping" by Marilynne Robinson, the protagonist reflects on her experience of love within marriage. She realizes that love often carries an intrinsic longing, a desire that persists regardless of the relationship status. This insight suggests that even when love is reciprocated and tangible, it does not entirely alleviate the deep-seated yearnings that accompany it.

This observation highlights the complex nature of love, depicting it as a yearning that can remain unfulfilled despite physical closeness or possession. The idea emphasizes the emotional and psychological aspects of love, suggesting that the essence of longing is an inherent part of the human experience, regardless of one's circumstances.
