Agree, I would NOT move back in until she agrees to work on the marriage with you. If she's giving you the old "I'm not sure what I want, so don't have any expectations of me", then I would give her more time to sort out what she wants.
If you move back into a situation where she expects to have her needs met but not meet yours (and that's what it sounds like), that's a recipe for hell on earth.
As HopefulStill suggests, you should have a list of reasonable conditions and leave yourself an out. The minute she violates your boundaries, move back out, so if you have an apartment, I'd keep the lease going so you're not trapped. Unfortunately when it comes to piecing you need to play hardball if you truly want to have a good marriage going forward. If it starts out one-sided it's unlikely that it's going to improve.
