In chapter 7, why is Daisy unable to say that she never loved Tom and why do you think Gatsby is unable to accept that she loved them both?
Gatsby is bent on conquering the past and all of his failures. Daisy represents both the past and his greatest failures and so Gatsby's attitude toward her is uncompromising.
Daisy wants to please Gatsby because she is desperate to recapture a certain sense of her own potential to be happy. Despite this desperation on her part, Daisy is unable to betray her sense of who she has been. She wants to change, but she is unwilling to remove all value from her past. Doing so would mean that her life was meaningless, that the future was all she had.
For all the characters in this novel, it is the past that sustains and not the future.
Daisy, whose voice Nick remarks, "sounded like money," is incapable of loving anyone; what she loves is wealth. What is the first thing that she does when she comes to Gatsby's mansion in West Egg? She buries her face in the many colored shirts that Gatsby shows her he owns. And, she cries at his wonderful material objects.
When she was a young woman and Jay Gatsby was a handsome officer, Daisy mainly loved his being in love with her. Later, then, after Gatsby goes off, Daisy does what all wealthy girls of social position did in her time: She marries a wealthy man and travels across Europe to come home to her new mansion and be "a silly fool." When Gatsby demands that she tell Tom that she does not love him, Daisy is unwilling to lose the wealth and social position associated with Tom Buchanan. Ultimately, also, she chooses wealth over the love and loyalty of Jay Gatsby who foolishly has viewed her as his "holy grail."
It is possible to love two people at the same time. Although you may love them in different ways, it is still possible. According to Daisy, she has loved them both--Tom and Gatsby. The fact that Daisy cannot deny loving Tom is a clear indication that she does love Tom or some ideal he represents. This truth is difficult for Gatsby to comprehend. He is so absorbed into his own feelings until he cannot imagine that Daisy has indeed loved Tom.
When Daisy cannot admit that she does not love Tom, Gatsby is devastated. He thought that he alone had Daisy's heart. Gatsby has been deceived all these years, thinking that if he had enough money, he could win Daisy's heart. Sadly enough, it is time for Gatsby to move on, but that is something he cannot force his heart to do. Gatsby goes to his grave loving Daisy, and she doesn't even attend his funeral.
Daisy is unable to say she never loved Tom would be a complete lie. She really does love Tom (in a misconfigured way). Gatsby can't accept this becuase he has always had this illusion of a "special" love between him and Daisy. Both him and Daisy have two very distinct definitions of love. Gatsby's view of love is absolute. He defines it in a way of complete loyalty in which Daisy has only and always loved him since the time they've known each other. It is a definition of character of himself. As for Daisy, her definition would be in a much more broad context. She can love many (Ex; Tom and Gatsby) while still be remaining loyal to both. Gatsby's allusion is held back in the past, he has always thought that the main reason Daisy married Tom was for money not for actual love. When he finds out that this was not true, this seems to be the "dealbreaker" to him. Both Daisy and Gatsby's definitions of love are opposite which is ultimatly the end of their relationship for this chapter. This illusion and pedestal for the future that Gatsby has held so high for both Daisy and himself is the end of his dream. This is why he can't accept Daisy loved them both.
