It's purely a matter of choice, and no-one's business but your own. I'm three years a widow, and still wear my wedding ring. I haven't worn my engagement ring for many years. I put on weight, and it grew too tight. I couldn't afford to have it made bigger, at the time.
My main problem is what to do with my rings, after my death. I have 2 daughters and three sons. 2 granddaughters and 1 grandson. I tried talking to them all about it, but they don't want to discuss what happens after I am gone. Do I decide now, and put it in my will, or leave them to sort it out between them when the time comes? A difficult conundrum!
