@jjohns,
I haven't been there, but can you look into day programs for her? It sounds to me like she's lucid and would enjoy the interaction, and would be relieved to know that she was going home at night.
You would get a break, of course.
And in the meantime, if you could get her a day program affiliated with a home, that would be ideal, as she could start to make friends there and, when everyone is in agreement, it should be a far easier transition.
