Raton - I am in the same boat as you. I overloaded my wife with TTATT and it was totally counterproductive - she went into full cult personality mode and shut down. According to my new improved apprach I don't speak to her about TTATT at all. I love bomb her and arrange family activities to do as an alternative to the KH.
It is a matter of using Witness recruiting tactics in reverse - love bombing and doing a good witness (by showijng through your behaviour that worldly peole are ntowaht the WBTS portays us as. If you are going to introduce TTATT I would use that approach rather than attack doctrine. Something along the lines of 'What did they say about worldly people in the WT study, Awake, Watchtower or in the meeting this week?' When they said that did you think of me? Do you think I behave in the way they say worldly peole behave? What about (name your familoy members who are not Witnesses who she is fond of) are they like that?' This should start to introduce doubt. Good luck
BU2B - hang in there buddy and keep up the good fight. Cheers Fraz
