No, she doesn't. That's the central piece of the manga and why its focused on the rent-a-girlfriend business. The fact that you can invest in a relationship and still fail is part of life, something Kazuya didn't accept at the beginning of the story, so he went for a service that better represent his views (you pay, you get what you pay for). The entire manga is him being a loser because he still clings to this idea when you can't force people to like you (and also the reason why he rejected Ruka, is the same thing but the other way around). Mami understood this and hence why she broke with him, she sticks around because she wants to see Kazuya maturing for once and becoming a man. The ending is the culmination of his ideals, Kazuya finally accepted Chizuru's decision and no longer has a breakdown like it happened before. And the fact that many people were expecting Kazuya to conquer Chizuru because he invested so much into this proves the author's ideas: Many people think like Kazuya thinking its transactional.
Rent-A-Girlfriend is a misunderstood social critique masterpiece.
