Is it a holiday that you celebrate or do you act like it doesn't exist because it was manufactured to make money for corporations and single people feel miserable? Do you celebrate with someone? Solo?
Are you an anti-Valentine's Day celebrator instead? Here's a link for that if you want to be inspired:

I enjoyed celebrating Valentine's Day with my husband when we were together; we usually spent our time together in private rather than publicly and we didn't do the chocolates / flowers / balloons thing. My nieces often sent me "Happy Aunt's Day" cards in lieu of Valentine's Day cards, the first few years after the divorce. I was grateful to be single but I also felt some sting that day, so that was really nice.
The last few years, being single, I didn't mind any of it but I still mostly avoided the stores even more than usual. All the RED EVERYWHERE and the candy and horrible but still sometimes tempting, toxic sweets displayed everywhere... I usually celebrated "Galentine's day" on a neighboring day via dinner out with girlfriends.
This year I'm in a relationship but he doesn't really celebrate holidays so although we'll be spending the evening together, I don't think it will entail anything obviously Valentiney.
My sister sent me pics of this card. As introverts, we both appreciate the sentiment. As frugal (cheap?) shoppers, the picture was better than an actual card.
