I was wishing today that I could just call you up and "talk you down."

Think about where you are now. Think about where you were 3 or 4 months ago. You know that he hasn't cut all ties with her, that he still calls her, which in my book is pretty much an EA, right? So the ring barometer is telling you what you already know, that he isn't all the way where he wants/needs to be. If he is still carrying on the EA then that must mean that he hasn't told OW it is over for good, you know that but she doesn't. And wearing the ring in front of OW would mean that he would have to let OW know that is OVER.

Which for whatever reason he hasn't quite finished off the dirty deed.

I don't condone his slick behavior either but I am not sure what purpose confronting him will serve, other than to let him know what you think he already knows... that he isn't wearing it all the time and it makes you mad and scared right?
