Mama, I agree that it's good to lovingly express your anger over his A. I don't believe that "loving anger" is an oxymoron, and you certainly shouldn't just try to hold all your anger in, because then it will eventually come out (at least for me it does), and not in a loving way.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
