'Why Is Your Ex Still Wearing The Wedding Ring?'

Leo and Rebecca Buzz Question ' Why Is Your Ex Still Wearing The Wedding Ring?' My MAN's EX still wears the wedding ring that my man got her back in the day when they were married. THEY ARE NOT MARRIED anymore so why does she still wear it in front of me. We see her at family functions and I try to be civil BUT she's pushing it. Should I SAY something or have my MAN do it? It ain't right....right?
