I don't completely fit your description as I have never been in. However my wife was born in and I have only starting sharing TTATT. So far she get defensive or ignores me. Up until recently I thought the JWs had some issues but once I really got into it I realized she needs out for her and for our kids.
My plan going forward is to take it slow. I could just show her all the information tomorrow but that would overload her and she would just be defensive. I have many topics but I want to be able to have new stuff to show two years from now if its still needed. I guess you could start by finding an old WT that shows one lie to begin with and share your feelings about her like you did in this post. Then every once in awhile come across another WT that bothers you and so on. I may not have really good answers. I am just starting on this myself.
