We are in the same boat and are concerned about our daughter. We are hoping we can get her to talk to a priest about this so she is aware of what she may be getting into.
My daughter is very concerned about it herself. I know she has reservations ...but she and this kid really seem perfect for each other — at this point. It’s a real shame. He 100% respects her Catholicism, but doesn’t usually accompany her to Mass. He has been known to do it, but not regularly.
If they end up marrying, I will only be able to pray for his conversion. She knows it’s all problematic. I feel badly for her.
However, we sent her to a very reputable Catholic University ..and who does she pick out? The ONE atheist/agnostic kid on campus!!! He’s a very good kid, though, and treats her like a queen. I am so torn.
