Daisy knew she was cynical. She was quite aware of her inability to love likely due to her husband’s constant affairs, therefore money had become her only stability.

Daisy loved Gatsby, but her experiences in life had taken a toll on her, and she had finally reached a point where, unlike Gatsby, she was no longer a hopeful young fool in love, but a woman who has done all, seen all, and who knows that even with Gatsby - in the end, neither of them may ever find the true happiness they seek.
