This would not be easy. I think the friend has serious co-dependency issues and well, she has to decide that she wants to be helped. This time, she should come to you. The last time you went but this time let her decide what she wants. You'd help her or anything she needs but she should come to you. I have never been in such a situation but that is what I would do if I was.
