When DH and I got together, we both wanted kids, but I was prepared to start like, right about NOW in life as opposed to 4 years ago. He changed MY mind. We're HAPPIER than ever. It can make or break a relationship. But you should either know for sure bfore you get married or come to terms with whatever and fill your life with something else. If that's what broke them up, it would have been something ddifferent, because if you're not on the dame philosophical/life route then something will pop up. I go to church, DH refuses to. We still both believe in God. We don't push our opinions on each other, but if he was atheist, and I washard core into my religion, it'd never work, even if we tried.
