HBF welcome to the forum ,i agree with other members here just back off a bit as far as your hubby is concerned but by all means celebrate your kids birthdays .don`t under any circumstances allow the JW/WT to get their claws into them .
Your hubby sounds like a typical average JW who has a feel good attitude about the religion and not one based on knowledge or facts .
What I would call a lazy intellectual belief in the religion .Don`t care too much about doctrine or dogma ,never really look into it ,just happy to hear about a new World where we can pat lions and pandas .
And worst of all they are happy to let others do their thinking for them , its so much easier .
My heart goes out to you ,I hope you have success in the long run in getting him out.
