Thank you for all the answers, suggestions and understanding.
Brija-del-sol, I am sorry, I know it hurts.
She is 16 now, they just had two weeks of holidays over there, which she spent mostly with jw friends.
I don't think she knows herself exactly, what she means by talk to me like before. Generally we don't talk (or write) about jw related stuff. About many other things. sometimes I think her links about things that I find interesting, I don't want to scare her, so it's nothing related to jw, just things that I hope help her to see how varied the world is.
In many things I think she is wiser than me, but she is also young and vulnerable. She is very intelligent, but also very emotional. She is the most caring person I know, from a very age on. I could imagine that she is scared that her safe little world gets shaken. She writes, she has to limit her contact with me, because I don't share anymore, what is most important in her life, because I turned my back to her friend, god.
She is very eloquent and writes beautifully, but I can see in which passages she uses exactly the words that we heard over and over again at the meetings, and in which parts she writes for herself.
I am reading one of Steve Hassan's book right now. Thank you everyone for the excellent answers!
