This is ana amazing song, but I think it's bitter as much as it it sweet. By saying that she is the sunshine- "You looked like the sun"- and then saying that the sunrise tried to end it- "the sunrise tried to end it while we tried to stay"- he's saying that she was the one who caused the end of the relationship, maybe unwittingly. All his heartaches have brought him back to her, but she doesn't- or maybe can't- want him.
