I was looking around for some prayers for wives, etc. and found one in here A Catholic Prayer Book by John F. Kippley that I liked. It's a great collection of prayers and this prayer will be another addition to my Daily Prayers page.
Prayer for My Wife
Heavenly Father, I thank You for the gift of (your wife's name). Help me always to see her as a gift from You to me. Help me to be the good husband and father You want me to be. Father, please help my wife to be the good woman You want her to be. Help her to grow in all the virtues she needs as wife, mother, and homemaker. Help her to be the real heart of our family, and help her to accept the leadership that You have entrusted to my care. Help us to be good parents and to grow ever closer as we grow old together. I ask this in the name of Jesus and in the power of the Holy Spirit. Amen.
