As far as the ring , my wife removed hers while we lived together. It was just another action which confirmed her affair. I kept mine on till I left 6 weeks later. More because it upset my daughter that my wife took hers off.
Now my ring means zero to me. It meant zero to her even though she continued to profess she missed it and loved it blah blah I'll trade the gold in at some point. Again it's entirely up to you but be under no illusion, wearing it don't mean sh1t to your wife. You need to get that in your head. She doesn't care. So if youre wearing it in hope she'll notice and suddenly coming running back....don't hold your breath. Me and lots of others have done the same with the same outcome. Sorry to be so blunt.
