Maybe it was fate. They just weren't meant to be. Only to be jaded friends instead of lovers. To break each others hearts a little more each time. To push each other into the back of their mind and only think about them on a rainy day.
Maybe they were meant to be broken. Never to be one and never to be whole. Fate is what makes their lives miserable. It taunts them about how they can never run away from what they feel but how they will always end up broken.
They talk to each other now, only when they have to, but they are always thinking about what could've been. It's a cycle. They are never on the same page. One of them wants it while the other one's faking happiness. One comes closer and the other one steps back. They never quite know what they want until its too late. Too late to go back and too late to change. But that is their fate. They will always be on different pages but that's what makes it exciting. That's what makes it worth having and that's what they miss. You may not be able to run from fate but you certainly can change it. It is never too late.
