My W stopped wearing hers long before I took mine off. I wore it as a daily reminder that I was DBing and still holding out hope that things could get resolved. I think it was about 6 months after we separated, I was out at a bar with some friends, talking to a woman who was showing interest in me. She understood my sitch but eventually said, "You know that wedding ring kinda freaks me out." So perhaps initially I took mine off to get laid (haha), but I think it was more about me trying to initiate a move out of the limbo I was in.
