I think most will tell you to let her deal with the consequences of her bad choices. Let her own it and let her move herself.
With that said, I helped my XW move out out of the same courtesy. I did have an alternate motive though as I wanted to make sure she did not take anything that was not agreed upon ahead of time.
I think it's a personal choice but I would let her own it. Unless you don't trust her. I did not trust mine at the time and still don't.
