One thing that really started to bother Mr Scully and me was the constant begging, pleading and bullying for money. Maybe it had always been there, and we just never noticed before, but it seemed like every week we were hearing about fundraising endeavours. For new Kingdom Halls™, for covering the expenses of the Circuit Overseer™, for covering expenses for Circuit Assemblies™, District Conventions™ and Special Assembly Days™. There were reminders about the World Wide Education Work™, the double dipping on Literature™ (pay when you pick up your materials, and turn in any Contributions™ received from Field Service™), etc., etc.
As a kid, I had it drilled into me that CT Russell stated words to the effect that when the WTS no longer received financial support, it meant that its purpose had been served. Clearly that viewpoint has changed dramatically over the last century.
Perhaps this can be one thing that you and your wife can agree upon. No more financial support for the Congregation™ or the WTS. Set aside any money that you would have contributed for say, the next 6 months, and use it to go on a holiday, preferably at the same time when a Circuit Assembly™ or Circuit Overseer™'s visit is planned. Say it's a holiday for your wedding anniversary if anyone asks. (not that it's any of their business...)
At the same time, start investigating child abuse scandals among JWs. There's plenty of them in news stories all over the internet, with court documents / testimony to back up the information. If there's one thing that your wife can't argue with, it's a conscientious decision on your part to stop supporting/boycotting an organization that pays lip service to protecting children from child molesters within their ranks. After all, the WTS bemoans the sexual abuse of children when it's Catholic clergy who are the alleged molesters... but when it's an Elder™ or Ministerial Servant™ or Pioneer™ who is accused of molestation, it's a completely different situation. The allegations are usually dismissed or not even investigated by Elders™ because there are not two eye-witnesses to the crime. How do you get the WTS's attention? You stop Attending Meetings™. You stop going in Field Service™. And, most importantly, you hit them where they live - by stopping financial support of the WTS at every level.
