I think it's about how a couple's going through a (long) "nightmare", and one of them (let's just say the guy) feels there's "something else waiting for you" because he knows that the other person deserves more. But then the girl leaves him all of a sudden, and even though he probably knew it was going to happen, he's totally heartbroken, with just her "holy ghost" (their memories). After a while, he starts to "keep on without you", but "prays you will come back one day".
Similarly, in the music video, it showed loved ones seem to be separated for some reason, making their lives seem empty. Both sides definitely miss each other, but they both want the best for each other, and "keep on without you", even though it still isn't the same because they are missing each other.
