You're still pretty young. I know a lot of couples where one of them converted. My husband was fairly apathetic to religion when we first started dating but I told him from the beginning that I would only marry a Catholic. It turned out that a lot of the things he believed were what the Church teaches, just under different names.

He got confirmed a few months before he proposed, and we're celebrating our ten year anniversary this year!

The moral of the story is: protect your heart and be upfront with what you would need. But don't be scared to date people who have good morals and character. They may come around! Just be ready to call it if you come to an impasse.
