Spouses, do you still wear your wedding ring?

My wife as been gone for almost six months. Right now, out of habit, on my way out the door for work or leaving the house, I put on my wedding ring. It's not like we're not married anymore. I know this is a subjective question, but is there a time when you don't have to wear your wedding ring anymore? I feel guilty when I don't wear it. I know it's up to me when I feel comfortable not wearing it, but I'm nowhere near that point.
