“You never loved him.”
Gatsby’s absurd expectations for Daisy are starting to drive her farther away. He should know that Daisy hates making the tough decisions, and he is forcing her into making the most extreme one of her life. If he was just content with just letting her choose between him and Tom, she would probably choose Gatsby since it seems like she has more actual love for him. But for her to choose Gatsby that also involves denouncing Tom, which makes the decision that much harder. So at this point Tom’s realistic expectations make choosing him easier to do, even though she wants to be with Gatsby.
