efforts in this book are focused on trying to bring him and Daisy back to the point of time before he joined the army, except this time he has enough money for her. 'She never loved you, don't you hear?' he cried. 'She only married you because I was poor and she was tired of waiting for me. It was a terrible mistake, but in her heart she never loved any one except me!' He wanted to repeat the past and have it exactly the way it was before he joined the army. She wasn't willing to risk her social status for the man she loved, concluding that she did not really love him. Near the end of the novel, Gatsby is murdered by the husband of the woman Daisy had killed.
Gatsby was denied Daisy's love and he thereafter paid for her actions. She walked away with her life and social status in tact and continued to live in luxury, paying no thought to the fact that the man she had "loved", was killed for an action that she herself had committed. Gatsby becomes delusional with the thought of Daisy. He again thought that he could turn back the hands of time and have everything the same and perfect, with the exception of a few dollars or so. He had no life anymore. She was his life.
It is also clear that the driving motivation for getting all his money, was so that he will appeal to Daisy. She was a material woman and she was used to living a lavish life. She knew that if she married Gatsby, she would have to give up many of the luxuries that she had become accustomed to over the years of her life. Gatsby's whole efforts in this book are focused on trying to bring him and Daisy back to the point of time before he joined the army, except this time he has enough money for her.
