You shouldn't change your core value system for someone else's sake unless you're absolutely sure you want to make that spiritual and emotional committment. My sister is a devout Catholic who married an agnostic Anglo-American (we're Hispanic). He's a nice guy, but in the beginning was hard. He did not want any children, or involvement with any sort of church, both of which were extremely important to my sister. She's been married to this man for 5 years now and seems happier than ever when you'd think she would be miserable. Some people can make that kind of change, others cannot. You have to decide not only if you can, but if you honestly really want to.
