Forgump sorry to that you are here. It is a terrible time in everyone's life if they have come to this board.
I cannot tell you whether to take off your ring or keep wearing it... No one can. What you have to decide is what message does it send to your S. Well she see is as: He has given up on us, He is pouting, He is trying to get at me, I still have him as plan B, Oh No what have I done he is seriously moving on. What do you wish to communicate by either taking the ring off or continuing to wear it?
I had the same question as you... I toiled over it and it kept me up at night. My conclusion was that I took it off when I realized it was over. The time I took my ring off was when I decided I did not want WW back. I could not forgive her BUT more importantly I realized I am better off without her.
A ring is a symbol. It symbolizes the marriage. You wear it on the left ring finger because it was believed there was a direct line to the heart. It is circular meaning it the M has no end. Wearing it is symbol as well and is communication. It could mean a 180 or it could mean departing from the M. You have to decide what it means to you.
