Daisy and Gatsby’s relationship is dark and complicated. It becomes “renewed” at two points throughout the novel.
Detailed answer:
From the very beginning, it becomes apparent that Jay and Daisy’s relationship is very troubled. They were lovers in the past, before World War I. However, Daisy decided not to wait for Jay and got married before his return. Of course, it broke Gatsby’s heart. Soon, he became obsessed with the idea of getting Daisy back. From the way Fitzgerald describes Daisy’s reactions, she barely remembers Jay. He, on the other hand, cherishes every moment they spent together. Gatsby understands that Tom and she are technically a great couple. Both of them are descendants of wealthy families, and they share the same values. Therefore, to attract Daisy, Jay has to achieve the American dream. He wants to lure her with lavish parties and an effortless, affluent lifestyle.
Across the novel’s timeline, there are two moments when Daisy and Gatsby’s relationship could be considered new. First, it becomes new the moment Tom learns that Daisy has been cheating on him. Apparently, Jay and Daisy are unbothered by that fact. They are almost happy to be finally open about their love affair. What works against Tom in this conflict is his own infidelity. His own adultery allows Gatsby to make audacious comments throughout Chapter 7. The second significant event is Myrtle’s murder. Gatsby is oblivious to what role Myrtle played in Tom’s and Daisy’s lives. All he can do is try to console Daisy. He convinces her that everything will soon be back to normal. At this moment, Jay lacks self-awareness. That is because it was he who rocked the boat of Daisy’s life.
