I know someone whose husband entered the Catholic Church after 15ish years of marriage. For many years the husband went to Mass with the wife and children, prayed the Rosary with the family every night, went up at Communion time for a blessing etc. The husband was very very interested in anything to do with Fatima on EWTN and would always stop what they were doing to watch it. This wife also put a green scapular inside their husbands’ pillow case and combined with all this, the wife praying for the husband to convert, it was not long afterwards that he did convert! Personally I think Our Lady of Fatima had a lot to do with it!
So never give up praying, don’t stop petitioning God. Perhaps you could pray the rosary together if he is agreeable?
