An important aspect of Marianne and Connell’s relationship is that they have grown up together and, consequently, have helped bring each other into adulthood. Marianne, for her part, is responsible for helping Connell broaden his horizons, since he was originally planning on staying close to home and leading a life that would have resembled his life in secondary school. If he’d done that, it’s less likely that he would have earned a prestigious scholarship, traveled in Europe, or gotten into graduate school. Marianne has thus influenced Connell’s entire life in an extremely meaningful way, which is why he can’t imagine leaving her to go to New York.
