I was a JW for 45 years, from the age of 4. My husband was one from age 15 until about 52.
So, it is possible. For us, it was very gradual and slowly seeing that the doctrines are not Biblical, for the most part. Dave was a very prominent elder and saw things that I didn't, in the "inner circle". The hypocrisy got to him too, and the beauracracy, behind the scenes, making him see that it is just another religion. It was a longer process for me, but I finally conceded and began to read some things.
So..........don't give up hope.
