She stands quietly by while he packs up. She could stop this at any moment, put a hand on his shoulder and tell him he can put his shit back. That it's not a big deal. Except it is. There's so little he seems to understand and whenever she thinks he gets it, his mouth spews out shit that proves her otherwise.

Space is needed among other things. All while he's packing her mind is racing with what she needs to do next. A change of locks is the best route to go, a sure-fire way to make sure he doesn't come barging in tomorrow because he thinks he owns the place. A place he has contributed very little to and hasn't shown appreciation for. She's worked her ass off since they got here to make sure they have enough, that he has enough and he throws it back in her face after barging in late at night.

So she let's him go. She doubts she'll be in the house for much longer, but she'll give him a good head start so he doesn't see her leaving.
