Dang, I don't envy you. I wish I had some words of advice, but I don't really as I have never been a JW. I desperately want to get my Mom out though. One thing is for sure- you can't go on living a lie. Try to help your girlfriend if you can, but don't stay for her sake because it will only end up hurting you both in the end. I've read enough stories here to know that much. Thanks for sharing with us, I will keep you in my prayers.
