I'm some way away, but they are welcome to come and lodge here for as long as it takes, if you can't find anyone closer.
On the other point - is the house in his name only? Because if not, she'd do well to take some legal advice before leaving, fraught though it sounds. And maybe talk to the council, because there is something about 'making yourself intentionally homeless' which makes them less likely to find you a place, though I think if she can show she is in fear for her safety, she would not trigger this. A women's refuge will have seen all this before and will probably have someone whoa can advise.
