MrSamurai is correct with his idea of what this song means.
I'd just like to add that the chorus
"that's what we're waiting for"
Is saying that, even though they are fighting against it, they are both waiting for it to get to the point where it is officially over and/or waiting for the part where each will no longer mourn over the death of the relationship.
And, in that respect, it is a love song. Not in the traditional "Come Back To Me" or "You Mean The World To Me" sense. It's more along the terms of "This is what happens when love reaches it's end".
