Thank you all for your interest.
Although I am not a religious person, I trully respect everybody's faith. I wouldn't try to change her mind about her religion even though I disagree with it.
But, I don't believe that, in her case, it is a matter of faith. I have read a lot of stories from ex-JW and most of them describe how they started having doubts about their religion when they descovered the inaccuracies that they were taught. I dare to say that my friend had never really believed all that staff (I admire her for that since she was raised by a very "faithfull" family). But she is socially and emotionally attached to JWs.
She is an intelligent young woman. And it broke my heart listening to her descirbing how her days are empty, boring and unfullfilling. She is married to a man that doesn't stop parroting their teachings and has no other interest than that. The same goes for the rest of her family. If I were her I would have gotten insane.
Of course she doesn't need facebook to contact me. She has my email, phone number and even knows where I live. She already knows that I am here to support her. I will not try to contact her again because I am afraid to causing her trouble. Leaving from there would be such a huge change in her a life that she could only handle it if she is sure about it. For that reason I don't want to push her. I am afraid of making things worse.
