At the beginning of Exit West, Nadia and Saeed were able to grow their relationship organically. They saw each other when desired and gave each other space when appropriate. However, when war tore apart their country they were forced to live together and then escape their home country together. While this living situation was manageable in the beginning, the lack of personal growth opportunities created an environment of mutual hatred.
This environment of mutual hatred between Nadia and Saeed is not just a problem among them, within the circumstances any “couple” would fall to the same demise. Being forced to live within the same quarters, without the space a blossoming couple needs, is detrimental. Nadia and Saeed were not afforded the ideal situation to grow. Nadia was thrown into the mix with the passing of Saeed’s mother and was almost “adopted” by Saeed’s father. This inadequate situation forced Nadia and Saeed to deal with circumstances a relationship of much longer length would have difficulties navigating. Their fresh relationship was not built for this complicated environment.
With this in mind, it only makes sense that both Nadia and Saeed would grow resentful of each other for the situation that was almost forced upon them. Such complexities only stunted their growth as individuals and a couple, proving the impossible nature of their relationship. In the end, it was bound that their romantic, and even platonic relationship, would fizzle out.
