It is a hard lesson, isn't it, but it's also a relief! You can stop holding on so tightly, stop fearing that things might end; you can let go of your need to be that couple who just celebrated their 83rd wedding anniversary and made it into the Guiness Book of World's Records, because even THEIR relationship will transform, and probably quite soon.
It's such a wonderful thing, too! How colorless and dull life would be if relationships remained static.
