If you are looking to create mystery then wearing your wedding ring might be the way to go.
While this sounds very clinical - if the wedding ring was a family heirloom (and wedding rings fall in to a different category than engagement rings as far as property goes) chances are she would have to return it to you anyhow.
I think I would take it off but that is just me. The day I noticed my H took his off was the day I took mine off. I don't really think there is a right answer as it is a very personal decision. To many a ring is a symbol of commitment. My thought process was my H took ever step to end his commitment to me and the ring was just the final "thing" so I saw no point in wearing mine. I do still have it and eventually will probably sell my engagement ring.
Do whatever helps you retain the strength and momentum you had y'day!
