I think it depends on what your status is and what you want to accomplish. Are you DF'd or DA'd, or just trying to fade? Are you trying to get your spouse out too? Trying to keep your marriage together if at all humanly possible?
I wanted to fade, to get my kids out, and keep my marriage together. I started fading when my kids were teenagers, and told them the things I had learned about the WTS. They decided for themselves that they did not want to be JWs when they were grown. But while they live at home, they attend the meetings and service, etc, with their father. They have never gotten baptized, mostly because I discouraged it when they were young, and because they haven't wanted to now that they are older.
Good luck to you in your situation!
