But how does she know that it would be better the other way? There’s an endless bifurcation of paths, and even with her overview, she hasn’t seen them all. Sure he didn’t live the life he would have done otherwise … and so?
She paints it as selfish to choose her own happiness, but fate drew them together, and she’s both ignoring that it was also his fate, and not asking him what he wants. Is the career she imagines him having without her really better for him than their love?
I like to imagine that the result of “leaving” is to end up back here again, but wiser. (Secret ending notwithstanding)
