As several have already mentioned, there's no cookie cutter, one size fits all approach.
When I first started lurking on this site about 14 years ago, I knew that I wouldn't last too long in the JW cult.
I was desperate to figure out a way to escape with my wife. I started reading posts from the beginning of this forum up through the years, looking for ideas that had worked for people trying to get their significant others out. I started noticing a pattern. Generally, when people would say something like, "I can't do this anymore, this weekend I'm going to tell her/him the truth about JW.", it didn't go well. The exception was situations like Tameria2001 described above. I read other forums and saw the same thing.
Because of the examples that I'd read, I decided on the slow, steady, tortoise method of trying to help my wife. At a certain point, I could hardly stand entering a Kingdom Hall, being PIMO was incredibly stressful for me. I was able to keep faking just long enough to help my wife see the "truth". Not long after we left I had an endoscope (stomach scope) and the doctor asked my wife if I'd been under extreme stress in the recent past (I was still knocked out). My wife laughed and said, "Yes, why?" The doctor told her there were scars all over my stomach from recent ulcers!
Was it worth it? My wife says that she's pretty sure that if I'd hit her over the head with things, it wouldn't have gone well. Once or twice a year, I'll get a text or a card from my wife that says something like, "I saw a car group out in field service today. Thank you for loving me enough to help me get out of that awful religion!"
