Hi Bells,
I was "hard core" once and there were people along the way that made me think.
It was a process though, I don't think I could point to any one conversation or person.
It was an accumulation over many years. What breaks the camels back will be different for everyone.
In the end for me it was the cold, callous attitude displayed by many in the cong that caused me to seriously question.
The conditional love, the judgemental attitudes, and moral superiority. It all felt wrong.
Your husband has been conditioned since birth to accept this behaviour as normal so he probably does'nt see it.
If your in-laws are happy being JW's the odds of them waking up are small.
Most people don't change anything major in their lives until the pain of staying becomes greater than the pain of changing.
Even then it is hard.
But all the best to you and I hope they wake up.
Sounds like you are doing the best you can with a difficult situation.
Sorry I couldn't be of more use.
