It just occurred to me this very moment that I never bothered to post my engagement on this forum! I've been engaged for nearly a year now. She's not Catholic; in fact, not anything. The interesting thing is that since we started dating, she's been very curious about Catholicism and even started attending Mass with me. As a matter of fact, she once went to Mass without me when she was out of town. In September, we began going to RCIA classes, but stopped when we reached the point at which one commits to conversion (though this was partly due to hectic schedules).
She has graciously put aside her expectations of living together before marriage and is very accommodating of my responsibilities, including that of raising our children Catholic. The amazing thing is that, ever since we started dating, I've felt that God is working in the relationship. Although she does not want to convert at the moment, I feel that the possibility is there, and I've seen first hand her spiritual awakening as our relationship progressed.
If there's anyone else who has married a non-Catholic, I'd love to hear some feedback about things that helped make your marriage a success. Obviously, a mixed marriage is not the Church's ideal, and I know it'll take some work and prayer. I'd love to hear how you made it work.
And, of course, your prayers, too. :)
