I always take songs and look for acoustic/live versions, I think that actually helps understand a lot about a song. And of course we all find our own meanings in any song. But I'd have to go with it having more to do with someone holding onto someone who really isn't there emotionally. One person wanting the relationship, striving for that perfection, but the other content being empty and without emotions or attachment. But still, no matter how cold the other person is, they are willing to keep trying. Of course maybe that is because of my current path I'm traveling, but hey, again, we all find our own meanings, if it's vampires or war. That's all you!
