My opinion on the ring thing is it's a personal choice. Steve has a point ceremoniously removing it has a manipulation aspect to it, but so does leaving it on. It's just the flip side, I'm married whether you want to be or not.
I honestly think you do what feels right to you.
I took mine off the second H wouldn't admit to the EA. I didn't want to be in a MR where he could lie to my face or that he'd rather call me crazy and insecure than admit he was doing something detrimental to our MR because he didn't want to have to give it up. I didn't make a big show of it. I just stopped. I felt like if he wants to act like he isn't married I have no real obligation to act like I'm devoutly and happily married out in the world. I wouldn't put mine back on until H showed a dedication to wearing his during Recon. I'm also mildly crazy so when he stopped wearing his ring I took it and put it away with mine. It "mysteriously" reappeared on his dresser when he decided to move back in to the MBR months after I had taken it.
It's something you have to decide. I just wouldn't make a big deal about it either way though. If you decide to not wear it don't tell him you're taking it off or why. If you decided to keep it on and he asks about it keep it simple, shrug and let him know you're legally still married. The end. No flourish.
