I personally think that the video means this: he slept with a girl and is going to leave her with a one-night stand just like he always does and that's the reason for what's shot in the motel room.
The one he's with in the motel room he hooked up with after he stayed with "Miss Jackson". When he found out Miss Jackson is just like him (sleeps around and then leaves right after), he lost his mind figuring out how much it hurt.
The lyrics "you've got him wrapped around your finger" means the guys that Miss Jackson hooks up with fall in love with her afterwards. He then drives to retaliate and find people bowing that have fallen in love with her.
Her sucking in the smoke is her taking their souls and she then takes his. then she gives him the sword realizing what she's done.
By her giving him the sword to stop the hurt she's been causing, it shows that she's giving up that kind of lifestyle. Therefore releasing all of the people dedicated to her i.e. the smoke coming out of her when he kills her with the sword
