Your average relationship. He's a badboy, the first verse tells us the way he treats her. Second verse tells us how she thought that she'd be the one to change him, that she was the one who'd make a decent man of him. Third verse is her acceptance that it hasn't worked, that is was a stupid idea to think that she could stop him being an asshole, and now she's cold. By the end, she stills sees herself as some sort of angel, despite her choosing someone who was obviously bad and admitting that, in the end, it was all just a stupid experiement to make her feel more secure.
