I would suggest just stop doing the physical touching altogether. From what you described it is you initiating it and she's just placating you by reacting to it. You've got to get to the point where she's the one initiating it.
Forget about the 180s for a bit. It comes down to what works and what doesn't work and obviously all the stuff you've been doing hasn't had any affect on her. You've got to do something that will rock her world to shake her out of her funk. Which is why I suggested you give her moving out talk before you left. However, because you told her that she could come with you, that blew that deal. You're easing her into her position too nicely.
Or to put it another way. In terms of what you're doing, "how's that working for you"?
