Sanchy welcome! Your situation is so similar to mine a few years ago, especially this part:
I know my wife will cut off "spiritual conversations" with me and so also will be gone my chances at trying to open her eyes. With my second child on the way, my wife has told me that if I am to leave the truth, she will teach it to them, regardless of my spiritual position. She also told me that I've made her life so much more difficult now, as she married me, knowing that I was a spiritual man; she never thought she would have to deal with this. Needless to say, this breaks my heart. I love her very much, and do not want to cause her, or anyone else pain.
My wife and I are still together and mostly doing well, we have the same problems other married couples have, but I know she's very unhappy I'm not the spiritual man she married; all my kids are out of the witnesses. My wife took them to meetings for years without me and taught them to be witnesses. I worked my tail off to teach them to be good, honesty and kind people who are not witnesses. My effort and the goofy doctrine of the witnesses and what my kids consider "weird and creepy" videos turned them off the witnesses.
Good luck Sanchy!
