I really feel for you. It does get to a point that you want to just stand up in the middle of the meeting and scream! I'm sure you've tried a lot of different things to get her to listen, however have you tried fighting fire with fire? What I mean is get out your bible and you it to show her that the Watchtower teachings are wrong. That is how I got my husband to listen. I started reading the bible a lot when I first left because I wanted God to speak to me not some organization or some person telling me what it meant. In Hebrews where it talks about those of faith Abraham, Sarah etc. It say they were all looking forward to their heavenly reward. That was the scripture that I asked my husband about. I read the chapter to him and said now where does it sound like they were planning on being after they died? there are a lot of other examples of various inaccurate teachings I could give you and if you just use the bible, she cannot refute it. This may open her eyes.
