Women are more invested emotionally so logic can sometimes be less important.
My husband learnt the TTATT before I did he was motivated to leave by the UN scandal and doctrines that he saw were illogical. I started to question the organisation when I saw the damage it was doing to my children, the way the literature prepared them to accept without question everything from the society. When I discovered the organisation had also lied about certain issues I was done and we left together.
It can take more for someone to leave if they have family and friends they may have to leave behind. At the moment she loses nothing by maintaining the status quo and she doesn't have to deal with the inconvenience of field service. She has the best of both worlds. You take her to meetings and provide company if she had to go on her own and make her own arrangements then she may feel differently. I would start missing more meetings and see if she goes on her own or whether she chooses to remain at home.
If you want her to wake up you need to tune into what matters to her and then if the society conflicts with her values then she has to justify it. Don't give her the information get her to think for herself and don't take platitudes and stock phrases as a valid justification. It is a long process for some. and it can be tricky since pushing too much may result in her having renewed zeal and clinging to the cult but doing nothing means that she will settle into a routine she finds comfortable with and see no need to change.
