James, if you were to actually marry her what would your fate be? Maybe she won't want a child because of the doomsday scare bit that makes them think the world will be annihilated soon.
If you do have children, she will bring them up as JWs. That is something you don't want to see. They will be isolated from those outside the religion. Forced to spend their weekends going door to door or looking like mannequins by a literature cart. And face death by not accepting a blood transfusion.
