I don't mean to be crass, but this:
So the other day she started saying thAT we will have to go our own ways when things get worse with this world.
would worry me more than the WT crap. This directly attacks her commitment to be married to you. I find that comment a little out of place.
but, where in the bible do they get this belief and how do they spin this to mean this.
I'm no expert, and been out for a long time, but the crap that they claim about that is the Revelation. I remember that greatly because as a 5 year old I started asking questions, horrified of the visuals of a prostitute having sex with a dragon. I was explained that the fornication between the prostitute and the dragon meant the relationship between religion and government, and that somehow both are going to end in the lake of fire, which gave me a visual of the then current governor getting burned alive (gee, I wonder how I made it out with some sanity!).
So that is not directly told in the Bible (you would think that such important part of the story would be better communicated). It's told through visions and those thins that John wrote while under the influence of something.
she will never wake up, i proved to her the other day that 607 bce is a false date...i did it using her own literature. but no dent....i have given her so much TTATT that it would make your head spin.
First, you just don't know that for sure. Second, you keep reasoning with her about what is written, words and doctrine. The reality is that many people in the WT don't even understand what they are taught, they just follow along because they are conditioned to believe whatever crap they are told. That may have been what woke you up, but that may not be what speaks to her.
Why is she a JW? If she's not born- in that religion, she didn't know anything about their teachings at the time when she got interested and decided to join. What spoke to her then? What got her interested? Whatever that is, that's what you should address. It still baffles me that people keep trying to (only) deal with the reasoning part of the equation to brainwashed people, without even remotely considering that there are FEELINGS, things that give them comfort, that make them feel good and part of that organization.
What does she value there? That's what you should deal with.
