i think the first verse is...about how they are both constant, no matter the shape, proof of this is in the photo album she wants back...there's no point in him keeping it because the pictures all end up the same...because of how long they have been together and how long they will be.
i think the "somewhere you slip, that is the way" part is...about how something goes wrong, that's when you realise how much you need each other.
but i think it's more to do with the photo album than you first realise...the line "a waste of time after all that we took" could be about the photos they took. dont make her a chapter in the photo album, she wants the entire album to be with her.
and in the third verse "if we did we'd only tear" like a photograph being ripped
