Lyric discussion by imnotgoodatusernames 

okay, to me, i think that this song is about someone (the girl) who is with/was in a relationship with this guy who doesn't treat her right and doesn't deserve her and is pretty much a douchebag and she totally knows it but despite everything, she really loves him and wants to do whatever she can to keep him around because she's not ready for the relationship to end and she's not ready to move on. and she knows that normally, someone would just dump the person and not put up with their shit but all she wants is to be with this guy and she doesn't completely understand why she so badly wants to be with him and waits for him and wants to do whatever possible to make him be with her even though he's not worth it and she knows she could find better.
