Love is like this, too. What my happily committed pal is saying, I think, is that one must become content with shedding a version of oneself that one might only vaguely remember but not be able to touch again. While my other pal has accelerated this process, shedding so frequently that there is no past self that can even stick around long enough to be remembered. Just a constant scroll of new selves to revel in and then discard.
