On the rent issue Rev, have you considered find a new place to live? It doesn't sound like she is coming back or you would welcome it, either.
Is it likely you'll suddenly be able to afford rent?
My thoughts are, even though it might be one more unstabling factor a new place may be a good change of pace, and a place you'll feel a new ownership over.
Tell her you're moving and her stuff is in a box on the curb, if she doesn't come get it.
I'm glad we are here for you and
extra glad you have a face to face support system.
