Yep mine was doing the whole independence routine just a few weeks ago. In fact she says that once we move she will super try to become independent which is a good thing as long as lines are not crossed.
I really have no good advice but to wait for reality to kick in. Show her lots of respect, and always remind her that all this was by her choice. Also expect her to come back with a long list of demands if she does. Some of these may sound outrageous to you, she is in wish list mode. Let life teach her some lessons. She'll be a better W for it too.
