This sounds like such a painful position to be in. I really feel for you, and for your friend. The best thing that you could do would be 1) to listen and let her know that anytime she wants help, you are there for her; and 2) call a domestic violence shelter or hotline and ask them what you should do. Then do it, to the letter. If you help her escepe without proper support, he could kill you as well as her. Much love an support,. Alle
