You do know how JW's are. He might be able to justify speaking to you as a way
to recruit the kids. WATCH OUT if he agrees.
You might need to debrief the kids after a visit to see if he violated any other requests
by taking them to the KH or telling them things about Jehovah and how their parents
would be destroyed unless we keep this a secret.
If it were me, I would use this as an excuse for SUPERVISED visitation.
"Dad, the kids and I would love to go out to lunch. They don't go without me."
That might be harsh, but he thinks he is fighting a theocratic war for their everlasting
lives so harsh might be correct.
Great job to the husband.
