It's in God's hands at this point.
I would say it's more important how you feel about it, than how your daughter feels. Are you comfortable dating non Catholics? My experience has been that there are faith-filled people in all traditions and denominations. It is more important to me to find a man of faith than someone who is just a nominal Catholic. Having said that, it is also comforting to have someone to share one's faith practices with. I don't think this is a moral choice. It's a personal one.
