“Happily ever after” is a myth because people, unlike characters in fairy tales, are not static. We live, we grow, we change. Happy, healthy romantic lives require not just continual reinvestment but constant awareness of the changes in our partners, our situations and ourselves. Our partners do not owe us a guarantee that they will never change, nor do we owe anyone such a guarantee. And as we change, so do the things that make us happy.
