Me and my bf are of completely opposite religions. He's a Christian where as I'm a Pagan. At first it was a bit rocky for us, with him thinking I was going to hell. It ended with me telling him. Just he started thinking about it and the fact he had no right to condemn me. Religion plays no part in our life other than when it comes to holidays with the family. His family is religious where as on my mom's side not so much. When it comes to holidays and Sabbaths, I celebrate Sabbaths on my own or with a few friends (mostly just one). I celebrate Christian holidays with everyone else. I have certain rules that must be respected by all others including my bf when it comes to my faith, but he understands and doesn't cross those boundaries. Other than that, our faith has nothing to do how we are as a couple and plays no major part. The only major part it would play is if we were to get married then it would include both our religions or no one's. That's something we both agree on fully. He's a non-practicing Christian.
