"Why do I care so much about him, and why do I wish I didn't?" reflects the narrator's internal struggle with her intense feelings for someone she cares about deeply. She is confused by her emotions and questions why a single person can have such a powerful impact on her thoughts and feelings, causing her to feel conflicted and overwhelmed.

This quote highlights the complexity of teenage emotions and the conflicting desire to be emotionally distant while still being drawn to someone. It underscores the universal experience of love, confusion, and vulnerability, especially during adolescence, as depicted in Stephanie Perkins' novel, Anna and the French Kiss.
