Secondly, in my opinion, this song is about an actual relationship and she broke up with him, but he wants her back, because he never stopped loving him.
Probably, he is "the sky" and she's "the moon" and he asks if "this what it's like ?" meaning, is this the way it feels when you have a broken heart ?
