A warning for Carla. He will miss the kids. In his JW mindset, however, he will try and convert them so they can join him in Paradise Earth. All protests will be brushed off as "opposition". He will do it behind your back if he expects opposition.
It is key not to freak out on a JW convert. If you do, you instantly grow horns and you enter the unsavory world of "Satan's minions". You will know when this happens because the convert will suddenly go all robot-like. It is a terrible thing to see. Every pore in your being will be screaming to drag the poor person out of that insidious cult. But you must not panic.
It's kind of like a Chinese Finger Cuff. The harder you yank, the tighter it holds.
JW's are primed to respond to mild, calm tones. It's the way they talk, they write. Imitate their calm style, and subconciously they respond to your direction. Slowly, gently, without setting off any Cognitive Dissonant alarms, nudge the ocean liner in to the dock. No sudden moves.
I dearly wish I could explain this a to spouse when his or her partner starts studying. Also, I think the ideal time to pull someone out is before the third week. We typically hear from a panicked partner shortly before baptism. That is waaaay too late.
...and as for holding the purse strings? I'm not parsimonious. I simply use it as a veiled threat. Without me, he has nothing.
