I’ve been doing the same thing throughout my marriage (over two decades) and with our kids since their births. One key difference is that I was clear about my nonbelief before we married and agreed that I would raise the kids in the family faith. I was also clear that I would not make any pretense about my views. So there was no sense that I had unilaterally changed the rules after the wedding vows, which could be an issue in your situation. But the fact is that individuals grow in different directions and at different paces within marriages, so marriages must bend or break to accommodate. I can’t say that the dynamic was, is, or will be easy in my situation or yours, but I do think it is entirely possible to survive and thrive if you keep the communications and the deals fair. Each of you is equally entitled to your respective beliefs. (Don’t let anyone tell you that religious belief trumps nonbelief.)
