I'm assuming that she's had that baby now, since you are back to talking about the Org with her? Having been pregnant many times in life, it's not the easiest situation to deal with, your emotions are all over the map, and it's an out of control feeling, being a host to another human. Not all women are glowing beauties lol....having said all of that, she was wise in asking you to back off till she knew she was out of that circumstance.
Now that she's not pregnant, it's not over. She feels like mother bear and that she has to protect her kids if you won't (leaving the ORG has been taught to her that you are NOT protecting or keeping her and the kids in best interests) You have to understand that she DOESN'T have doubts. She was fine in her little world, looking forward to spending eternity in paradise. You are threatening her hope and her dream.
WE know her hope and dream is a lie, but try telling that to HER if she doesn't want to see it.
My advise is the same as others, seek legal council. Try to make a truce with her. Try to ask her for her to disprove a point at a time for you, to help you see it as the truth again. Shelve it and don't speak about it ever again, and don't go to the meetings with her. Just become mum on the whole thing. Whatever it takes to keep the peace, and try to reach this woman I'm assuming you love greatly.
If you love her, then you should do whatever it takes to keep her, UP TO THE POINT of living a lie. You wouldn't ask her to do that, and she can't or shouldn't ask you to do it either. Its not fair.
I hope the best for you here, and welcome.
