Lorde is talking about herself and her past relationships and what people have said to her presumably before ending a relationship with her: she's too much to handle, she's too wild, and this comes as no surprise when her newest love interest cuts ties with her, she's heard it all before. This guy is breaking up with her for the same reason everyone does and she just has to learn how to love herself, which is the girl she sings about in the first verse; even if no one else loves her, she'll always have herself.
