Stand your ground. Don't do anything, if you are feeling that what they are forcing you to do is is destructive to you. They don't care about you, but about the "image" of the Cult.
You don't believe in JW, so the so called "ELDERS" have no right or any authority to shovel you around.
They can be very nasty and persistent. If you think that you marriage can be saved, try some other consultations, what both of you can agree upon.
But stand your groung !
