"I saw something today that has made me remember that we won't always have each other to hold, talk to, love, play with or even just aggravate every now and then," she added.
"This picture speaks loudly and it may hurt your heart as it has mine. This man looks like he is spending Valentine's Day alone at first glance but that is actually his wife in that very beautiful bottle sitting on the table.
"Apparently his love for her was and still is very strong as he takes her ashes out for a Valentine's lunch date together. He even bought her a glass of wine... Please love your Sweetheart while you have the opportunity, you never know what tomorrow will bring or take away," the woman wrote.
The image was shared more than 240,000 times in less than 24 hours.
"This is by far the most touching thing I've seen in my short 17-year life," a Facebook user commented.
