It seems like he broke up with her, and she's making fun of him to herself to try and get over him, telling herself that he's worthless without her. The brass knuckles seem indicative of a weakness he feels he needs to compensate for, hence why he dumped her, to make himself feel like he has control. But later she finds out she was right about him needing her and finds him endearing. But she also thinks herself crazy for wanting him back now that he's a wounded animal.
The video also kind of paralells this, her subtle delight in the various actors' break downs. It comes off as creepy and cruel, but the lyrics show that maybe she has a reason to be mean if he's been so crappy to her.
