You may not think this now but god your lucky!
We desperatly want to make a clean break and get out, but we have grown up kids still in and I cant take the risk of shunning.
I am so full of remorse for not seeing the truth when our kids where little.
I know it must be hard for your wife, if her mother has stopped speaking already and im not trying to minimize it, but in our case although half my family are in the org, if it wasnt for my kids id leave and risk the shunning from them
The strain of leading a doulble life when you are fading is sometimes unbearable. When things get bad, just look at your children and their future and be happy youve done the right thing
Keep us posted and good luck
