loving you is killing me

what do you do when the one thing you did right, was him. what do you do when he was the only good thing in your life.
when he made you forget what hating yourself felt like. when his smile could instantly make you forget about the bad day you were having. when he made being sad seem okay as long as he was there to go through it with you. what do you do when he made you feel all these beautiful things you thought were only found in fairy tales, then one morning decides that you're not what he wants anymore and leaves you wondering why your best wasnt enough?
