My 2 cents:
Figure out how deep she is in. When und why did she join this religion? Does she have worldly friends? What about her family?
If you're lucky she might be a "liberal" JW. My wife is one. Her best friend is a muslim. She was willing to marry me, an unbelieving mate, although she knows that people look down on her for that. She puts the needs of her family above the demands of her congregation, for example not going to meetings when one of our children is sick. She knows that she is considered a spiritually weak person but it doesn't bother her much.
