This is the truth of the world: you can spend years devoting your time and love to someone. You can take care of them willingly and happily. You can think you know them as well as they know themselves. You can trust them entirely. But no one, absolutely no one, will ever change unless they want to, and some are incapable of change- no matter who they are, or what they meant to you. Broken people will always find a way to justify their selfish ways. There is no such thing as a promise.
