My wife is religious. I’m sure what to say about it. It’s a non issue in our lives. She thinks what she wants. I think what I want. Kids were a little tricky, but we worked through it. They got introduced to the idea of religion when they were younger and I made no bones about not believing and we agreed they could decide for themselves. AFAIK they are both atheist but who knows when they experience significant loss - a lot of people turn to religion then. The older kids from her first marriage are all believers I think but also pretty casual I think. I think my oldest married an atheist, but the truth is I just don’t have reason to talk about religion or lack thereof with anyone.

ETA: we were married by a pagan. I also married my daughter dressed as Darth Vader after dueling her husband for her hand. So it’s just not a big thing.
