Looked down and it was gone

Just found the data that confirmed my husband had been to this one woman's house. After copy, pasting, and sitting there looking into space with racing thought, my last thought was that im going to keep my ring no matter what. I looked down at it and discovered it wasnt there. Ive been looking everywhere and still havent found it. The coincidence and timing of it disappearing is trippin me out. Ive never lost it before. It had been loose for awhile and has been slipping off on occasion, but for it to be missing? (I did hear something yesterday that made me think something metal had dropped from my hand, but i can't remember anything else yet.)
