Story split in two

The story of Exit West was one of the most interesting that I have read, as it was both an introduction into the genre of realistic fantasy and also that it seemed to so perfectly reflect life in ways that many other books fail to accomplish. In reading the last few pages of the book we learn that Nadia and Saeed drift apart and eventually become their own people and normally this would be considered a sad ending as the two lovers split apart and go separate ways but I think the way the book it written it is all about finding your own way in order to live a life that is best for you. This relates to the even bigger theme around the book which is migration and that is isn’t alway about the story but rather what you do with your life. As Nadia and Saeed separate they become more and more themselves discovering what it is they really want to do and how they want to live their lives, this relates to that topic of migration as while the story of the people is relevant it is less about that and more about the fact that as people they want to start a life where they are that is not home but rather that they are in a new place and would like for that to be a new life. While sometimes migration is about escaping the old it is also about starting new and why would you leave somewhere just to live the same life twice?
