I'm never surprised to hear of that situation when it happens because I have considered it myself. My best "trusted" friend who is also "OUT" says he "fakes it". He attends about 50% of the meetings and all the special events with his wife who is a diehard JW (in a hypocritical way). That way they maintain all of their friends and social contacts and social status. He doesn't want to compromise the relationship with any of his kids who are still "IN" and married to JWs. (None of them are diehards, but it's their social network too.) It works for him.
I made a couple half hearted attempts at it in the past before my wife fully awakened. It was torture to sit through all the 5th Grade level drivel BS at the meetings. I was afraid I would be "outted" by my facial expressions or by the dozens of times I would roll my eyes at the BS "from above". But I truly do miss the association -- the social interaction from several who were close friends. And you can tell who the real friends are because they are not shunning me (I'm inactive -- NOT DA or DF). You know how they treat us "weak" inactive members.
My wife has now fully awakened and we're on the same page. She too misses the association with old JW friends. And making new friends on the outside is difficult. First, because it was sooo easy making JW friends, because it was "automatic". You're a JW so you're their friend. Easy. As long as you remain a good JW.
Well, there is no "automatic" friendship in the real world. Making a real friend is real work. Most people's friends are from school, college, work, sports, hobbys, etc. We avoided making those friends when we were JWs because they were "worldly" and could put us at spiritual risk. So, for us, we are 40 years behind on building a network of real friends.
Fade. Fake. Whatever works for some, might not or will not work for others. Your mileage may vary. Many here have strong opinions one way or the other. Do what is good for you and your wife.
Good luck,
Doc
