I don't think it's about a 'whore' at all, just about a girl who is in love with a guy who treats her like dirt. Although she sometimes thinks she is over him and can start moving on, she is actually weak on the inside and the second he calls her she is right back by his side where she started. He may physically and verbally abuse her, but this doesn't stop her from wanting and needing him, something which you see a lot of in relationships. She isn't a whore, that's just his perception of her because he can do what he likes and still get her to cater to his sexual needs.
