Give Sister Suzanne a call. You don't even have to tell your spouse. I'm not promoting deception but you may just want to do this on your own. On the other hand, you may want to tell your spouse that you are interested in learning more. In that way he or she may support you or help.
New life is a precious gift.
We praise God for the gift of salvation and new life in His Son and we thank Him for the love He shows us through each and every one of you. With sincere affection, Msgr.
