I know how you feel. I'm in the same situation like you. I tried to keep my family together but I just couldn't. There is a year we are separated now.
My wife turned me in for apostasy...yeah she loves WT more than me.I tried to show her that WT are a banch of false prophets that they care only for power over their followers. She wouldn't understand. or she didn't wanted to understand.
You know what has WT become: A BIG CLUB
That to be part of it you have to follow their stupid rules...they have their friends and partys, and pic nic, and their "spiritual" gatherings. They don't really care about the truth.
When my wife she couldn't answer to my questions in many subjects regarding WT she was just closing the doors of her mind. Brain washed robots. That is what they are. We had a lot of arguments and shoutings after my desfellowshiped. I was a stranger in my house. She was telling me not to come early at home because she had party, and you know who are the guests..I had to live the house. I didn't wanted to do it but there was no way other way.
Our first daughter got married, and I wasn't allowed to attend at the wedding. I have to small children 2 and 5 and it really hurts me to see them grow in that insanity of the WT. It is the most unhealthy inviroment for kids to grow. I know it from my self because I was raised as a JW. I'm trying to show them when I can that God is love, and is not a KILLER like WT thinks. I pray for them so God one day will open their minds. That is all I can do. I know my wife is guided by the 'elders' of this cult. They are telling her what to do in every single step of her life. I know that I don't have power over my children,and they are owned by the WT. I hate it so much. By I pray that Jesus love will overcome WT.
It is hard for me at the age of 40 to start again. But I WILL NEVER GO BACK. It is madhouse there, and I will kill my self.
Try to be close to your kids, and teach them the God of Love. In most cases our story leads to divorce. You just can a normal home with the WT in your ass. That is a fact.
