I don’t think I can do it. I can’t marry Tom. What about Gatsby?
Gatsby vs. Tom
Daisy, tell him you never loved him, you just love me! Tom, she is leaving you, you don't know what you're talking about.
He looks like an idiot in that pink suit!
Who do you even think you are? You're crazy! My wife loves me and has always loved me.
Tom vs. Self
I'm going to lose Daisy to Gatsby, too! I need to do something.
I'm going to lose Myrtle to George! They are going to move and I will never see her again.
I don't care if my wife wants to or not we are getting away and going to the west!
On the night before her and Tom’s wedding, she is found crying over a letter from Gatsby. She is obviously distraught and torn between marrying Tom and her love for Gatsby. Her decision in the end to marry Tom shows how materialistic she is because she would rather marry someone with money who is not a good person than someone who is a good person but doesn't have money.
At the Plaza hotel, Tom becomes extremely angry over Gatsby and Daisy's affair. Gatsby tries to get Daisy to tell Tom she never loved him, however, she tells him it would not be true. Gatsby and Tom go on fighting until Daisy breaks it up by insisting on leaving. Gatsby's attachment to the past gets in the way of him accepting the fact he is not the only man in Daisy's life, while Tom's need to be in control causes him to lash out and make accusations against Gatsby.
Tom starts to realize he is not in control like he feels like he needs to be. George Wilson is going to take Myrtle to the West, so he is going to lose her, and then Daisy and Gatsby are having an affair, so he is going to lose Daisy, too. He realizes he needs to do something if he wants to remain in control.
