I focus mainly on myself and trying to find my own happiness. While I would never turn down a JW seeking help, I don't spin my wheels trying to have conversations with people heavily into their cognitive dissonance. Of course, I will always try to help my wife and my mother. The biggest help one can give family members that don't shun you but don't want to hear any anti-JW talk is to encourage them to think for themselves and try to reach their true-personality (the non-cult personality).
I thought that my wife was a strong JW when I was an active JW. But as it turns out, she was holding on to my coattails. Once I wasn't going to the Kingdom Hall, she still went but felt free to be "running late" or would occasionally skip meetings. She started cramming her WT study in the car while I was driving with the radio on. She gets a minimum in the field circus. She's still a total believer, but she doesn't keep up with what they teach her to believe. She is attempting to make new friends, but it turns out that they are JW's that don't know me. I wonder that it is because the JW's that know me treat her differently now that her husband is "inactive." That is a huge help to her seeing what conditional friends she has.
