What Is The True Relationship Between Daisy And Tom In The Great Gatsby?

In “The Great Gatsby” Fitzgerald explores different forms of love and admiration in order to bring the reader to the conclusion that the relationships found in the text are flawed, corrupt and marked by deception, adultery and overall dissatisfaction. An example of such relationship can be found through the marriage of Tom and Daisy Buchanan.
Fitzgerald seems to take a sombre view of marriage in general, possibly due to his own relationship with his wife Zelda. Daisy appeared to be somewhat in love when they first got married, but the realities of the marriage, including Tom's multiple affairs and harsh treatment, have worn on her. Daisy and Tom Buchanan’s relationship is based on wealth and material possessions, and lacks a passionate love that only offers them an empty, materialised version of happiness which imperfectly binds them together. In the first chapter, Daisy says “I’m p-paralysed with happiness” upon first meeting Nick. If looked into further, this could show how Daisy is trapped in a relationship that is fundamentally perfect with money and station, but it lacks enough adequate passion in order to amass any actual happiness.
Tom cheats on Daisy with his mistress in order to make up for the dissatisfaction that he feels in his marriage with Daisy. Daisy merely resents the situation in silence and does not lash out, nor conjure any plan to leave Tom; she simply accepts it, which further perpetuates her own dissatisfaction with the marriage in addition to her inability to escape its promises of wealth and status. Daisy had made her own decision to marry for the gain of material wealth over that of happiness, and in doing so, had doomed herself to be stuck in a position where “neither of them can stand the person they are married to”. Daisy’s discussion with Nick in chapter 1 reinforces the idea that Daisy is quite depressed and feels confined within her marriage; at first glance, it seems that Daisy is revealing the fissures in her relationship - Tom was “God knows where” at the time of the birth of Pammy, their daughter - as well as a general disdain for society, “everything’s terrible anyhow”. This means that Daisy, due to her own experiences within her relationship with Tom Buchanan, has come to realise the true nature of the world around her; because of this, Daisy wishes for her daughter to, “be a fool – that's the best thing a girl can be in this world, a beautiful little fool. Daisy’s desire for her daughter to be a 'fool' is actually a desire to shelter her from experiencing the pain that Daisy herself has known in her marriage.
