The quote reflects a woman's realization about the dynamics of love and relationships. Initially, she believed that maintaining a close, perhaps possessive bond was essential, akin to how a mistress might behave. However, over time and through her own struggles, she came to understand that a wife requires a different approach, one that embraces subtlety and freedom rather than control.
This insight leads her to a pivotal conclusion: allowing her partner the freedom to explore other relationships may ultimately reinforce his affection for her. It highlights the complexity of love, suggesting that space can cultivate appreciation and comparison, ensuring that she remains his "incomparable queen." The passage reveals the transformational journey of the character as she navigates her own insecurities.
