I would wear your wedding ring if that's what you feel is right. It's a personal decision that I wrestled with a lot at the beginning of my stich.
Don't wear it to show her you won, or because you are trying to make a point to her. Let your feelings guide what you do, and whatever you do, if you remove it, make sure you are taking it off because YOU want to, and not because of how she will respond. And don't start taking it on and off. That will show weak boundaries and weakness is not attractive.
