Hearts are crushed even more by her stubbornness, as willful self-centeredness seems to suit her very well.

This couplet captures the delightful paradox of being in love with someone proudly obstinate. The poet notes that while the beloved's sheer stubbornness crushes fragile hearts to dust, this headstrong defiance suits their grace remarkably well. It is a tender, helpless confession—grumbling about the cruelty of their ego, while secretly falling in love with the effortless charm of that very pride.
