its not out of the ordinary. pretty much the same for all of us. my W hasnt wore her ring since before she dropped the bomb. she would take it off when she left the house, put it on when she got back i guess. i know it hurts, there is nothing you can do to MAKE him put it back on. he will if he wants to.
i know how hard this is right now. i've been there and somedays still am. bond gives great advice. he has helped me alot. keep trying, dont give up. one way or another you will get through this.
