Well you've already dropped the Hassan/BITE references. Maybe be prepared to talk about a specific point on how cults use family ties to control cult members. The family/friend thing was a huge issue for my sister. When she would bring it up, I would ask her questions about how she felt a true friend should act. We talked about unconditional love quite a bit too.
Talk about what types of relationships are of value to her and why. And then give her options outside of JWdom to begin filling that need.
edited: To change "cultivating" to "filling". Ugh hate that word, CULTivating.
