I tried to set a consequence of her leaving the MBR, but when she said she wasn't leaving I wasn't sure how to handle it. I don't feel I can really force her out if she doesn't want to leave. I could move her stuff out, and she could move it back in. I almost told her "she could move her stuff into the guest bedroom or I would move it to the front lawn for her", but that felt like it would be too much. Should I fight harder action-wise to get her out of the MBR and hope she yields first?
EDF,
Eat two cans of baked beans one hour before going to bed. She'll leave on her own.
