Religion?

My fiancé and I do not have kids yet nor are we TTC. This is just a "what if" kind of question. I am a born and raised Catholic. While I do not stick to every rule (who does anyway?), my religion is very important to me. I, also, grew up attending private Catholic schools until high school. My fiancé, on the other hand, grew up in a Baptist home. He stayed with the church until moving away to college. Now he is just a Christian. Here's my question: how would we raise our child? I would love for my kid to be raised in a Catholic home but I feel like my fiancé wouldn't want to convert. What are you doing/have done in this situation?
