I don't wear mine. He was still wearing his a week after he left, but by the following week when we went on holidays he had taken it off. I wore mine for the entire holiday, but took it off and wore it around my neck when we got back for a week. When I found out re the OW I took it off completely and it hasn't been back on since.
