All I want in life is Daisy. She is my one purpose in life.
Daisy is told by society that she must marry soon, and that she must marry rich. She is told from the beginning that money is what she should look for in a man. This is what creates her materialistic personality. She conforms into societal norms by marrying Tom, which meant marrying rich.
Constantly fighting an internal battle, Daisy struggles between choosing a man. Tom or Gatsby? She feels so alone, so "deserted". She confirmed she loved them both, and she is conflicted, and she had an affair with Gatsby. Daisy's marriage was filled with lots of infidelity and she struggled a lot with this throughout the novel.
Gatsby is extremely conflicted throughout the whole course of the novel. He is in love with a woman (Daisy) who is married. His "American Dream" is to be with her. He is in love with her, and she has an affair with him. Gatsby's dream is never fulfilled, and he never gets to be in a relationship with Daisy, considering that the only relationship he had with her was a false affair.
