A good friend of mine is travelling in South America with her partner, with whom she's always had a volatile relationship. I've just sent her a Facebook message asking how things are going, and she replied and said she's had to go to hospital and have stitches because he punched her and broke her nose. I've told her to get out, but she says it's not all his fault and he feels terrible about it, and that she has nowhere to go. I've offered her money for a flight home, or just to somewhere else, but she says that'll only "make things worse". I'm worried for her mental and physical health but I don't know what I can do. Any ideas?
