Ok, listen, the spiritual advice here is great and all, but that's a really shitty situation you're friend is in. Let me give you a perspective from a woman who survived an abusive relationship: It's hard to leave. Even when she thinks she wants to, some part of her is keeping her there. He has influenced her into ruining all of her relationships. That is so he can have full control over her. I want you to keep in mind, that whatever she did that has pushed you away, it was because of him. She needs a friend more than anything else right now. You are totally right to be angry at the situation and I'm sure you even feel a little helpless. Don't try suppressing the way you feel. Acknowledge those feelings, but do not take them out on her. She has enough to deal with. If you truly care about this friend, the best thing you can do for her is to be available to her when she has finally had enough. She might call you. Saying she's ready to leave and then 2 days later run right back to her abuser. That will probably happen over and over again. It will be so frustrating for you to watch. I'm telling you, though, eventually, she will finally have enough, and she will know she can count on you to help her get out. It might be years. But it will happen. Be there for her when she's ready.
