I would be tempted to go in because it would be hard to watch and not be able to talk (or shout) to her. I don't think I would be able to sit at home and wait for her, I would go in and tell her off along with Steven then walk.
On the other hand I would probably be far to upset to even see her and like the other poster said, I would keep my dignity and just go in with my life or at least try to.
