EWTN Catholic Q&A
Question from Linda on 04-25-2012:

How do you forgive someone who has hurt you deeply when they are not sorry or don't even seem to care? This is someone I love a lot but they seem to love themselves more than anyone else. They were not raised in any faith and God is not important in his life.

Answer by David Gregson on 11-12-2012:

The best thing you can do for anyone who has hurt you is to pray for them. God willing, they will come to see their error and repent of it. This is particularly important for those who have no faith. They need God's grace to turn to Him, and your prayers may make the difference.
