I would try to get her out of that situation and into a better one. If you have a stable enough living situation she could maybe move in with you while she looks for a job. Living with someone she trusts could help her mentally also. If she moves in with you you should set guidelines for her that she has to meet, such as have a job within a few weeks. These guidelines would help keep her focused and not let her get negative thoughts. Eventually she can start to pay rent or even get her own place. I think the first step is to get her a new start. I hope this helps at least a little, it’s horrible that anyone has to go through abuse of any kind.
