“Just have her in mind three times a day, when davening vlamalshinim. “
Does she qualify as a Malshin? Does saying L”H make one a Malshin or does it need to be said to someone like a corrupt gov’t official who will do something bad?
I’d rather pray for her return. See Brachot 10a, where Bruriah told her husband to pray for the return, and not the demise, of wayward Jews. His prayers worked.
