Hi, Cindy:
I was in/am in exactly your shoes. I discovered TTATT and it was a devastating shocker to me. My husband is an elder and fairly zealous but not unbalanced. Essentially, I just did a very long, slow fade and here I am, inactive for about eight years and never happier! We kept out marriage together and just agreed to disagree. In fact, my husband helped me in my fade by running interference between me and elders who wanted to "talk" to me (we know what that means). So I never had to face official questions or anything like that.
It's hard--don't get me wrong. I let my field service time dwindle, as you are doing, right down to an hour a month and then, one August, I just didn't turn one in. And guess what? Nothing happened. About two years later, we moved to a different state and that made everything even easier.
The point is, you WILL get through this. It is quite possible to make a happy life for yourself and keep your marriage intact. And coming here and getting support is part of that.
