The quote reflects the profound transformation of feelings that can occur in relationships over time. The speaker expresses a deep sense of confusion and loss, once believing they felt an all-encompassing love, only to find themselves filled with resentment toward their first spouse. This stark contrast prompts introspection about the nature of love and how it can evolve or dissipate completely.

The author, Raymond Carver, invites readers to ponder the complexities of human emotions and relationships. The speaker's longing for understanding suggests that love is not static; it can shift dramatically based on experiences and time. The desire for an explanation reveals the struggle many face when trying to reconcile past affections with present realities.
