I can really sympathize with you. I would not quite describe my wife as lukewarm, but she is a cradle Catholic and seems unwilling to advance beyond the religious practice that she was exposed to as a child. I long for the day when she would be open to daily Mass, rosary, etc.
I am praying for you and your husband.
Remember, O most gracious Virgin Mary,
that never was it known that anyone who fled to thy protection,
implored thy help or sought thy intercession,
was left unaided.
Inspired with this confidence,
I fly unto thee, O Virgin of virgins, my Mother;
to thee do I come, before thee I stand, sinful and sorrowful.
O Mother of the Word Incarnate,
despise not my petitions,
but in thy mercy hear and answer me. Amen.
