I agree with OldSkool that the singer is already dead, but by killing himself after his lover left him. It took me a few listens to figure it out, but then I realized it would make sense. "The neighbors have guessed" that he's dead "'cos [he's] canceled the milk, and they don't hear your voice through the walls anymore" because she's left him.
"Each second seems like a lifetime" because in death there's no sense of time, I suppose. And "the cat has been staring" at the body. It seems like the spirit of the person is aware of what's happening and talking as if he was still in his body.
