Do not react and don't do or say anything. As hard as it is, simply ignore it and don't try to over-analyze why she did it or what (if anything) it means.
Once she is moved out, feel free to get it out of sight if that helps you. Whatever/Whenever you choose, make sure you're doing it because it feels like what you need and not because you're trying/hoping to get a certain reaction out of her or trying to read her mind.
You're right. And I was kind of thinking that as I was typing, so it will stay until she moves.
