how about not 'pushing' but rather saying when she is ready to explore things you are here for her.......
tell her you know 'a few things, inconsistancies and such'...
AND
Get her to see it for herself. Don't tell her, help her to get it out.
the 2 above quotes from previous posts are spot on in my opinion,
i was terrified when i started to have doubts and i actively avoided people i knew would help me leave cos i was needing to slow it right down, and looking back i needed the space and time to gather the strength and courage to be able to leave without feeling that terror,
i started having doubts because of inhumane treatment of individuals on a couple of occasions that i just could not ignore, it got to that part of me that wasnt brainwashed and it started the ball rolling, although slowly,
just be there for her, be a great husband!! so that you are her support network NOT THEM, so that when and if she leaves, she will know she can survive it,
is ther anyway you could move away from the area thats having a big effect on her? i did that too, and i t really helped me to leave, not having the pressure of a congregation and family right on my doorstep.
and yes just get her to say things, they say that a really good teacher gets the pupil to come to the answer themselves and that that is the best way to learn, but you can nudge her in the direction of it,
