Thanks for sharing your touching story. I have a similiar one. It is almost 16 years and I still miss her so much.
I got an email from one of my Sisters just a couple of days ago. She said she thinks of Mother every day. I do too. I have also noticed that my dreams often have Mother and Daddy in them.
They were married just under 70 years and were never separated except when Daddy was in WWII.
