Divorce is often/usually 'wrenching.' When a church or religious organization encourages it, based just on belief difference, it is revolting.
Where was that Awake from their own writings?, stating that no one should fear losing their family if they change their religion. The WTS is a big hyprocrite that way, on their long list. They don't help people, and the children, well, I really feel sorry for them.
Dale, I hope you can be building your health, physicial, emotional, spiritual, to build a relationship with your children, proving to them the kind, loving person you show. Helping to create their own mental thinking, as age appropriate. Instill them to love their mom with respect. Find wise 'gentle' ways to help them be aware that there is a good, positive life for them.
Help build, good fun times for them to have good memories of their youth. For sure, JW kids don't look back with fondness on all the brain-dead meetings and door-to-door work they had to spend. Try to get into 'city' sponsored activities (museums, zoos. parades, sports activities) to do together, often not expensive.
Maybe if your wife sees how you pour so much good energy into the kids, she will re-think. If not, at least your kids will love it. Unconditional love, your kids will not hear, nor see in the WTS.
