This may be an urban legend. But even if it IS it's pretty damn romantic. Or creepy, depending on how you look at it. 

A clip from a magazine has been going around online. It looks like it's from 'Redbook.' It's a story from a 68-year-old woman in Houston, Texas named Sue Johnston. She was married to her husband John for 46 years, and every Valentine's Day, he'd send her a bouquet of flowers. After 46 years together, he died.

But the next Valentine's Day, Sue STILL got a bouquet from John. It made her angry and upset, so she called the florist to tell them about the mistake. But they told her, 'Before he passed away, your husband prepaid for many years.' He asked them to keep sending her bouquets every Valentine's Day. And when Sue looked at the card on the flowers, it said, 'My love for you is eternal.'
