i feel like this song is trying and then not caring about being accepted by people who should accept you no matter what.
like you do something or are something that isn't accepted by them and you're waiting futilely for them to call you and tell you it doesn't matter, that they accept you for who you are. However, then Marina realizes that this is stupid because she shouldn't need to grovel for someone's praise and love and acceptance when they should've accepted her from the get go. So she's saying "It's not me that broke your heart" implying that that person chose to make a big deal about it that would ruin their relationship.
