What goes around comes around. That's what people say. So all the pain you caused me will come back to you someday.

There are some people who meet that somebody that they can never stop loving, no matter how hard they try. I wouldn't expect you to understand that, or even believe it, but trust me, there are some loves that don't go away. And maybe that makes them crazy, but we should all be lucky enough to end up with somebody who has a little of that insanity. Someone who never lets go. Someone who cherishes you forever.
There is always one person you love who becomes that definition. It usually happens retrospectively, but it happens eventually. This is the person who unknowingly sets the template for what you will always love about other people, even if some of these 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.
