I am in an interfaith marriage. I am the non-Christian believer, dh is the Christened atheist.
Sorry, but what you are telling us is a massive red flag.
Had neither of us been able to compromise in order to build our lives together, I would have run a mile.
I am less practicing than I would like, he is passive but respectful during our rituals. We joined a faith community that would accept dh without reservation (although there are some specific rituals he cannot join - but he doesn't want to join them anyway). My family have accepted him wholeheartedly, because he is a good man and that's what matters.
I wanted a faith marriage, but that was not going to happen unless dh2b converted. I did not ask him to. He is a grown man, knows the situation, and it's up to him. So we had a beautiful and honest civil ceremony. Both families participated fully.
Anything religious that was important to me, I made sure we had discussed and found a solution to before we embarked upon it.
Neither of us lays down the law to the other.
