Dear Married,
My father went though the EXACT same thing you are discribing, but because he did not take the time to develop a relationship with us kids our only option was my mother and her religion. Work on your relationship with your kids, take them one by one out for breakfast or fishing or something where you have one/on one time. Do you really think your kids enjoy sitting at boring meeting? Readiing 3 grade material? Knocking on doors, and most importantly feeling limited in who they can become as an adult? Please believe me about this. Be interested in their education, take the lead by getting them involved in school activities or other sports or hobbies. It is easy for your wife to take the lead because she has the comfort of a cult to support her. That is NOT being a parent. A real parent takes the lead themselves. It is going to take work, but I tell you, your children are not stupid. You give them an option to the JW cult and they will go for it.
