There is always one person who you love who becomes that definition. It usually happens retrospectively, but it always happens eventually. This is the person who unknowingly sets the template for what you will always love about other people, even if some of those lovable qualities are self-destructive and unreasonable… The person who defines your understanding of love is not inherently different than anyone else, and they’re often just the person you happen to meet the first time you really, really, want to love someone. But that person still wins. They win, and you lose. Because for the rest of your life, they will control how you feel about everyone else.
