I just wonder, when two people "grow" but their lives are no longer intimately involved, do they not tend to grow in different directions? And at different rates?
So two people may have connected on some levels when they were younger. Then they live different lives and face different challenges, and when they meet years later, I would expect them to have even more differences than when they broke up.
But maybe not? I'm too young to have experience with that
Maybe all people grow at different rates but eventually end up at pretty much the same place? They do say that people become more conservative with age, for example.
