In "Loyalty in Death" by J.D. Robb, a character grapples with feelings of unworthiness in a romantic relationship. Despite knowing that their partner loves them, they are unable to understand the reasons behind that love. This uncertainty creates a sense of instability, as they feel caught in a cycle of self-doubt.

The character's anxiety over their perceived inadequacies leads to a fear that their partner will eventually discover these flaws. This fear acts like a barrier, making it difficult for them to fully embrace the love they receive. The internal conflict between love and self-doubt highlights a deep struggle with self-acceptance and vulnerability.
