I would say that the longing you feel to be Catholic is God calling you to Him. When it’s God doing the calling, I don’t know of how one can ignore that. Your wife is scared because of what she thinks she knows about the Catholic Church, but she is scared by ignorance. I would say just be the happiest, most thoughtful, wonderful husband you can be, and let her know the light you shine is from the joy and happiness you have found in Catholicism. I think talking to a priest is very good advice.
This should have been posted in Non-Catholic, there is a group ( On Tiber’s Shore ) who are longing to be Catholic, but finding nothing but resistance from family. They know what you are going through and can help you with advice. Praying for you and your wife. God bless.
Blessed Mother, please intercede for us.
Hold the sorrowful-
Mother and love the weary, abused, neglected
or forgotten among us-
Give your aid to all needing help or healing-
Assist those who are sick, in pain or suffering-
Be with those needing peace-
Console the lonely or brokenhearted-
Comfort the lost or hopeless-
Strengthen the fearful-
Guard the unborn-
Pray for those who are dying or who have died-
Soften those with hardened hearts-
Enlighten those who do not yet see truth-
Help us be brave enough to let our hurt and anger go-
Show us the way to do the right thing-
Protect those who are in danger, and
Guide us from every evil.
May all who keep your sacred commemoration
experience the might of your assistance.
Amen
