In the quote from Stephenie Meyer's "New Moon," the speaker expresses deep frustration and sorrow over a misunderstanding in their relationship. Despite having expressed love countless times, one negative word has shattered the other person's trust. This highlights the fragility of emotional bonds and how easily doubt can undermine feelings of affection.

The speaker is taken aback by the belief that they no longer want the other person, describing it as an irrational idea. They emphasize the importance of their connection, asserting that their existence is intertwined with their love. This underscores the theme of reliance and the emotional turmoil that arises from miscommunication in relationships.
