I understand how difficult it is to figure out what to do with wedding ring. Mine is in a little envelop in my jewelry box tucked away. It seems tainted and something I'd never want to have near my body. I always wondered why some divorced women felt so good about making their diamond into a necklace. Perhaps if in the future I'd put it into some type of setting that has other gems (diamonds included) so it doesn't stick out. Right now it feels right to have it out of sight.
And the emotional chaos of divorce is exhausting. My only word of caution is that it's not about his needs; that if he wants then it's over. Divorce begins in the mind. Focus on you. Your needs in moving forward.
