Christian spouse

Hello everyone. I have been an atheist for quite some time, but do consider myself to have some spirituality. My now husband was aware of this when we started dating and was okay with it. He grew up Christian but wasn't really religious when we met. 5 years later, he has now gone back to being an active Christian. I am petrified of what this is going to mean for our marriage and parenting. He already can't stop talking about bible teachings and Christianity. I don't want any part of it and it's making me feel uneasy. Any words of advice or personal experiences?
