What happens to the heroine in Guy de Maupassant’s Boule de suif?

In the short story Boule de suif by Guy de Maupassant, the heroine—a prostitute nicknamed "Ball of Fat"—is traveling through Prussian-occupied France during the Franco-Prussian War.12

When a Prussian officer detains their coach and refuses to allow it to proceed until she submits to him, she initially refuses on principle. However, her fellow passengers, who are "respectable" bourgeois citizens, pressure and manipulate her into satisfying the officer's demands so that they may continue their journey. After she yields to the officer, these same passengers treat her with coldheartedness and contempt, ostracizing her for the remainder of the trip. The story serves as a sharp critique of the hypocrisy and moral shallowness of the bourgeois class, contrasting their behavior with the heroine's authentic generosity and principles.12
