In the first 5 lines she’s questioning how loyal he really is. She’s asking if he would get hurt for her, show affection, and do whatever she wants.
In the next 4 lines she's talking about this person taking pleasure out of her pain. And, I think, is sadistic in the way that he mistakes this brutality as love; “I bet you kiss your knuckles/right before they touch my cheek”
And for the chorus she is singing about finally taking control of this sadistic/abusive relationship and deciding to leave finally; "but I've got my mind made up this time"
