Hello Bryan,
I am in the same boat. I was raised a JW and I actually brought my exwife into the org way back when. Our children have attended meetings since birth (3 girls), and I now have custody of them because of the abuse going on in their mother's JW home. The middle child, 15, still attends meetings pretty regularly on her own, and I have talked to them many times about my decision to leave the org for good.
I sometimes have the impulse to kidnap my own kid and take her to cult deprogramming experts, but I know I must be patient and let her see things for herself, and I think this will take time. The other two girls are at the point where they see it all as bs and they attend meetings only sometimes if they get board want to go flirt with cute young brothers (it makes me laugh). Hang in there and choose your opportunities to talk to her and have some sort of documentation handy.
As crazy as it might seem, the hidden and subliminal images controversy is what began to open my eyes to the lies. It might be a good place to start. I got creeped out enough to start asking harder and deeper questions about that and other issues, and it sparked some really good conversations with my kids about their experiences with the JW's.

Good luck and my thoughts are with you.
