I pray for them both, and their spouses, when I say my Rosary. My middle child is married to a great guy who adores her and they have 2 gorgeous kids. She’s done everything right in her life, while the other 2 have always chosen a more difficult path. I love all 3 the same, but it’s hard to watch those 2 make such heart wrenching choices for themselves. I have to hope that everything works out the way it’s supposed to in order to put my mind at ease.
From my own perspective as a “bad kid,” try to feel reassured that they will probably straighten up at some point, maybe in the near future. They’ll need you for something.
