This is a song about a relationship that's breaking up. About how a relationship can deteriorate although you don't want it to... and how you can still be with them but notice they're not into you anymore, and that although you still love them, there's no way to work it out. And when your beloved is drifting all you're left with is a "boring kind of anger" and sleeplessness because the person you still love is there but is not really there.
