I used to care when I had a lot of time on my hands.
DH and I have been happily married for 14 years...he lost his wedding band when we were out together over a year ago. We were both CRUSHED. This was the ring that was blessed before the ceremony, etc. We called pawn shops, etc. It came to me realizing the ring is just a symbol. It almost felt phony to just buy a replacement. I have entertained the idea of getting a new one as a surprise for a monumental anniversary, e.g., 15, 20 years, etc. I might even go the priest and have him bless it again (even though we aren't terribly religious).
For now- I've gotten used to him not wearing it and nobody else has even seemed to notice. Trust me--my family would say something immediately if they noticed

. In over a year, at Holidays, etc..nobody has noticed.
We joke that hussies tend to hit on men with wedding rings more often than those without anyways

. It was a running joke with my DH's friends when they first got married how many women would come up to them when out with the new wedding bands.
I don't give a cr*p what some yenta, like one of the pps, thinks of seeing DH without one....esp when we've been married so long now.
I have taken to not wearing mine as often now that I work at home full time. I always take it off whenever I am in the house and now it is much more comfortable without. I also lift heavy weights at the gym and it can be uncomfortable then.
