I don't want anything to do with you anymore. Go back home to Tom.
I want you not Tom , why do you think i'm here right now?
Okay then Gatsby...
Well i don't feel the same. I think you should just leave now.
With text evidence I found in the story , I believe that Gatsby is going to tell Daisy that he doesn't want anything to do with her after she hurt him. It says "he made is nervous circuit around the house" You could infer that he was nervous to fully get rid of her for good. It also says that " he walked into the house glowing." You could infer that he was happy about getting the job done and getting rid of her. You can use all the tect evidence to prove this.
