I heard a story today which hit home.  A woman was praying for her husband to repent on his bad ways for ten years with no result.One day it was suggested to her that she  should pray to be able to serve him and be a proper helpmate for him as the Torah requires. From that time on  she began to wash his socks and laundry and help him in other ways. And in fact he also began to change for the better

What was interesting to me was  that a prayer for someone to repent is not a bad prayer. It is much better that praying for some enemy's ruin and destruction.  Still apparently even to pray for a bad person to repent is not a good as wishing sincerely for oneself to love them and to wish to serve them.
