JUDI8751- You asked, " Is there a syndrome for this ? " Yeah, it's called dangerous " cult mind control".
The WT society has these witnesses under a spell keeping them there through intimidation tactics of fear and guilt to make them stay tricked by the society's false promises. It's really that simple. But the typical JW - unfortunately your JW husband included - don't know what's being done to them in a manipulative way. It's really sad. I hope your husband can break free of this slavery someday
