Lady Lee, you hit it on the head. If you read my first post, you'll see that what you said is my life in a nutshell.
The first shock that sent him back was marriage...it didn't stick (mostly I think because he couldn't quit smoking).
The second shock that sent him back for good was our beautiful baby girl. This time he quit smoking (because I had quit before I got pregnant so he didn't have it around) and he's been super dub ever since.
I threatened him with divorce because he was trying to indoctrinate my older daughter by having 1/2 hour sessions with her on Sundays (he was reading the "My Book of..." with her) and he told me that he wanted to take our little one to meetings. After I told him to get out, the 1/2 hour sessions stopped (his reported hours must have plunged...) and he has made no more metion of taking our baby to meetings. After I told him I wanted a divorce, he refused to leave...after all, "Jehovah hates a divorcing". I don't know whether he won't leave because he'd look bad in the congregation or because he couldn't get remarried because there was no adultery (unless you count the fact that he's having an affair with an organization).
Now I am just existing in our marriage. I try every once in awhile to throw something out to him so he can see the light, but I fear he's too far gone. His mom became a JW after her hubby left her when my JW was only 7 or so. She had three kids (7, 6 and newborn) and they jumped on her. So, he's about as bad as a born-in JW as far as social skills and education. I have tried to reason with him, fight with him, shock him (the pedophilia cases). Nothing works. He just goes blank. I actually think that his involvement with the WTBTS has caused him some mental illness. It amazes me how fast he can get mad then turn it off on a dime.
And that's all I have to say about that...
