I suppose that I am of two minds when it comes to this:
If it involves a live-in/shackup situation, then I would tend to agree with pirata in that there is little that can be done and that the situation will resolve itsef one way or another.
If there is a marital situation, it can be much more drawn out and painful. I would then tend to agree with LouBelle. Try to get a dialogue happening. Openly honestly and factually discuss what's wrong with the JW religion and the people who ardently follow it. If discussion fails, the marriage will fail as well.
In any case, there is no way that I would be able to tolerate being in a close relationship with someone who is normal one day and then becomes an associate of JWs the next. It would be far more than I could bear, considering that I've left that stuff behind and have no desire to put up with JW rhetoric inside my own home. If I ever date an XJW, I would have to pose the question of whether she would have any inkling, desire or reason to return. IF she isn't firmly committed to leaving her JW past behind, my commitment to her will be left behind instead...
