Hello Barry. Try not to read your Ws mind about why she does anything. Doing so will hurt you and likely lead you down cheeseless tunnels.
I have taken off my ring. For me it a reminder that I'm moving on with my life. While counter-intuitive... R success stories show that it's when you let go of your old M that you make room for a new M if possible with your W. If you are being tactical... it could send the message to your W that you hear her and are not pressuring her to come back.
Others do as you do... wear the ring as a sign that they are standing.
It's up to you.
