So sorry you are in that situation. I too had a countdown going...conversations with my kids at 14 and 16 had me in the same boat. Fortunatley for me and them, they did not get baptized and have both abandoned the JWs.
what really boiled my blood was learning that the elders had told him that he had to curtail his time with me...even though the law said he had to see me.
I told my son when it looked like was going to commit to them something like this: "that that will be your mistake to make and trust me, you will live long enough to regret it. The fact that you won't let me explain why they are wrong is going to be your problem, not mine."
