Honestly. Even before the song, she is smiling, teasing him. She is hurt and mad, but abov all, she loves him. THAT'S why she is hurt. She loves him, and he messed up to a degree she doesn't understand. That's why she keeps asking him why. The song is them seeing each other.
why the fuck do i see people say via forgave stolas too easily when the whole entire point of her being mad is because SHE FUCKING LOVES HIM. she wants her dad!! shes mad because she thinks her dad left her! "im so tired of hating you" BECAUSE SHE DIDNT WANT TO IN THE FIRST PLACE
