In our case, I woke up first but for the sake of family, I stayed. I noticed my son had issues with the JW's teachings and reassured that I would never turn his back on him should he one day decide to take a different path in his life. So, when he was 16 he informed us that he no longer wanted to be a JW. Few months later, my wife got me in trouble with the Elders for an essay I wrote. Despite the "apostate" label I carried from then on (that eventually led to a JC later), and my wife knowing my thoughts about the Org and the "truth", I persisted in staying for the sake of family and friends we had in. Then, it was my wife's turn to wake up after a night of insomnia led her to go online and be shocked with the paedophilia problem within the Org. Next morning, she told me she would never go back to the meetings. Henceforth, we never went back. This decision from my wife was blamed on me ever since, and this unleashed a JC for apostasy. I was able to successfully defend myself and I was only "reproved". So:
1) Husband first gets mentally out but stays in for the sake of the family.
2) Son gets mentally out, and then takes a stand to leave.
3) Wife suddenly gets mentally out and takes a stand to leave.
4) Having accomplished the deliverance of his family from the cult, the father also takes a stand to leave.
