I take it from the comments that you are still with the mother.
I think its go time. You need to make a clean open break with the religion. Ask yourself, do you want your kids contemplating this same scenario when they are older? Do you want them to regret being taught a lie for 20 years and then having an epiphany at 20, 30, 40 or even later?? Hell no!! You cant teach your kids to think critically by reading a book and then live a lie. You need to step up for the kids sake. I am not saying its easy, but what is the alternative?? I look back and ask "how did my mom teach me this bs?" They are only kids once, give them the chance to play a sport, be on the debate team or whatever else they are into and just be a normal kid!!
Fading is living a lie. That is not judgemental . I know some faders and I know why they are doing it. But one of the reasons I woke up is because of the thought of having to explain to my kids some effed up things that do not make sense to me. They will learn above all else by what you DO, not what you say.
I feel for you bro, not an easy decision for you.
