Ynot:
His 5 year old first need is for stability in their home.
You might noticed I mentioned his wife and his daughter not trusting him.....
While his wife will more than likely be wary for several months, his child will probably be ready to follow his gentle lead within a week or two (maybe less if she has been a 'daddy's girl').
I believe I saw on the other thread he said he had ordered "Teach Your Children How to Think".
It is far easier to begin teaching such if he remains married to their mother.....
If he doesn't go back (or at least appear to be trying) he will remain suspect to some extent.
I have seen JW children dismiss their unbelieving parents ......his daughter very well might be the type to go that route because she feels in her heart that is the right thing to do......
His wife is already showing some classic reactions...... pushing these buttons will only lead to more division and disharmony....and all the 5 year old is going to discern is 'its daddy's fault because daddy doesn't love and obey Jehovah and he is trying to get me to do it too" ....daddy is already cast as an 'enemy of Jehovah' in her mind.....so falling back, recreating trust allows him to replace that negativity in her mind and allows him the opportunity to lead her to critical thinking and knowing her daddy loves her, he is trustworthy, stable, predictable and strong .....he keeps her safe....daddy isn't the 'bad guy'.
It seems to me that going back is not an option for him. Again, the Watch Tower isn't God, nor does it have the strength of the law of the land. Both Anon ymous and Mamalove have custodial agreements that legally bind the jw parent not to attempt to alienate the ex-jw parent. Hopefully this will become a growing trend. But the OP will never know if he has this possibility until he consults an attorney.
IMO, protecting the kids is the goal here. Pussyfooting around a cult isn't going to help them. Taking a stand by teaching the kids critical thinking skills and giving them an opportunity to experience the real world is the only way to help them out of the indocrination.
