The song, if you ask me, is about a girl who is trying to break up with him. She thinks that this will be somewhat of a big deal to him and tries to break the news to him gently(And she said it's not you I just need my space). The light tone of the song and the rest of the lyrics lend to the idea that it's not an issue to him and that he'd rather start anew, because he knows that he'll be just fine without her.
