Perhaps a bit more information would clarify things, Another Guy. Do you know if she has been baptized? I would guess not, if she is only "getting into it" now. How old are the 2 of you? Are you looking for a casual girlfriend, or are you thinking that you might like a more serious relationship? How does she feel about her parent's mixed relationship?
Part of growing up and maturing for her is deciding whether she want so live the Witness religion/cult and culture. It sounds like she is exploring that option right now. You have received excellent advice from some of the posters here. If she is at early stages of indoctrination, it may be possible for her to break free, with your help. Remember, by turning her back on the JWs, she risks losing all her JW family and friends, and they may shun her depending on how hard line they are. It is a huge choice with enormous consequences for her.
Should she decide that she wants to stay with the JWs, make sure you separate and move on with your life. Even is she left for you, but still believed, the situation would be very risky. Unless she is completely de programmed, there would be a high risk of her going back to the JWs someday during a period of stress in her life.
Remember to protect yourself. Try and free her if you wish, but if it isn't working, it is time to move on to look for a healthier relationship.
