I suggest you do some reading on it because you need to take your significant other seriously when she tells you she is right to be very upset about this stuff.I am taking this seriously. Two days ago she was threatening to end our relationship and "show me the door". Believe me I am taking this seriously.
Poor guy. Freaked you the heck out didn't it?? Let me guess. You stood there in shock as the mother of your child turned into a paranoid lunatic in front of your eyes??
Trust me, you can't understand the level of panic a WT escapee has when confronted with the idea that their JW family members might suck their child , their SO, and themselves into the most high control religion I've ever had personal experience with. You just can't.
My husband became a JW after we were married. It came very close to destroying our marriage. After a couple of years, I quit fighting it and joined myself. It was awful. We eventually left, and have been out for around 15 years and married for 25. We never had children, fortunately.
If he came in the door today and announced he was rejoining JWs (which he would not, thank goodness), I'd divorce him. End of story, no second chances, no trying to salvage the situation. I won't go back to that and I won't be married to a JW man again. EVER. It's really that bad (especially for a woman).
You can't imagine how easy it is for someone to be sucked into this group even if they have their guard up. My guess is she's not only worried about your baby, in the back of her mind she probably thinks if you can't see the danger you might be sucked in too (she may not even realize she feels this way).
Educate yourself. And remember that the stories you hear are only the tip of the iceberg. Pregnant JWs have been advised to "tap" their bellies to discipline an unborn child who won't hold still during meetings. Seriously. Parents with babies in diapers are reminded to take the diaper OFF to spank them if they won't sit perfectly still and be quiet through 2 or 3 hours of meetings (there is no nursery in a JW hall).
You don't want your toddler to wake up screaming because he had nightmares of himself, you and his mom being destroyed by Jehovah (look at some of the pictures in their "children's" book some time).
Be on high alert.
