Hey there,
You are going through hell right now, and your hubby's head is messed up and indoctrinated too. But you must keep your child best interests first before your own and your hubby. Keep your child away from the atmosphere and keep things stable. If you can't do this whilst all in the same house you need to tell your hubby it's no good for your child and give him an opportunity to be a kind, loving man.
You may be right he could be absorbing all what you have told him and come to the realisation it's all nonsense, but to have a lifetime of belief taken from you it traumatic, it was for me when I realised it was nonsense. You also may be right that he thinks you're an evil apostate sent by Satan, and he should have listened to WT when they told him to "marry in the lord"
Take a few days to evaluate and keep us updated.
During this time, spend time shopping with your child, swimming, painting nails, going for a spa, fun girlie stuff.
Take care love Kate xx
