Welcome, Stumpy. A hearty Texas howdy to you and your wife.
What you and your wife are going through was the same for my husband and I. We were"in" for over thirty years and he was an elder for twenty years.
When we finally realized it just couldn't be the truth, we were bewildered, depressed, and felt like the rug had been pulled from beneath us. In our case, we'd put family at a long arm's length for many years, never spending much time with our parents, and then only grudgingly, feeling that they were hopelessly dupes of Satan. By the time we woke up to the truth, they were dead.
We left about ten years ago. By now, we are on a much better track. I went to college and graduated at 61. I am a teacher. My husband enjoys hobbies he could not develop before.
Please know there is abundant happiness and life after leaving. Wish your family the best.
