Fading is not an option for everyone. He tried that already, nowwhat?.
To P.E. I don't think that there are any defined phases. We all get to the point of leaving the org in different ways and realizing the truth about it is not always rolled into that, so we will all differ.
I do think though that its safe to say that you are barely out and everything is feeling a lot more raw now than it will in years to come. Everything in your life now is colored by this, but soon it will just be an occasional distraction. You know it isn't right. Check. You have your daughter nearly half time. Check. Your social life is a clean slate, and your baggage doesn't involve a criminal record, so you are way ahead many folks. Just keep moving forward. Don't let this cult be your focus anymore. Your future and that of your child is what matters now, so work and build for that. Actively go out to make friends and companions in activities or sports that you enjoy; Put extra into your work and get WAAAY ahead of the game.
Do well and be happy. It's not about revenge, its about living your life.
