I have missed you, I regret marrying Tom, i really love you.
I am so happy to hear that, I have always been in love with you.
I wonder how its going.
I believe that Daisy and Gatsby talked about how Daisy is unhappy with Tom and how they both are in love with each other. The quotes "Daisy's face is smeared with tears", and "Gatsby was confounding. He literally glowed;". I believe it takes a lot of emotion to explain how you are not happy in your marriage which explains why Daisy is crying and Gatsby was glowing which I assume means that Daisy feels the same way about him and he is now relieved and happy.
