Personally, I would continue treating her as a guest, unless she offers to do something specific, or you want to "hire" her for paperwork and such.

Seems to me she has more than enough going on without her host pulling a cinderella number on her. She isn't there by choice, or to hang out with friends. She's there because she's in a screwy situation, which already sucks plenty without adding housework.

I think it's nice that you were offering her some companionship, talking and stuff. That might help her feel comfortable if she wants to talk (she might not).

Glad to hear your leg/hip has improved.
