you're not replaceable
life isnt an mmorpg where every person is a specific class with a certain level.
you're not a character sheet.
if i lose someone, ill never get them back. i cant make a comprehensive list of traits, find another person with those exact traits, and think they'll replace you
because they're not you. they're not the relationship we have. they dont have the history and experience with other people that you do. (and this applies to relationships with other people too, not just me.)
