Triangles of Love, like fins on a mermaid

I just finished watching The Guernsey Literary and Potato Peel Society. A moving story to be sure. I have a soft spot for British period pieces during or about WWII, so it was an easy fit.Except that it wasn't because it had my least favorite trope. My qualm is the dreaded love triangle.I didn't warn of spoilers because even if you haven't read the book or watched the movie, the cover of the book gives away that love will be an issue.While I appreciate the plot device--it does ramp up the drama and add bittersweetness to a story--it's overdone. And always done to a woman. I'm not saying it's sexist, but when was the last time the story involved a man and two women (or a man and two men or a man and a man and a woman)? I searched the files in my brain and couldn't think of a single one.Then I remembered The Little Mermaid. One of my least favorite Disney princesses, but the original story had a love triangle, although the object of the triangle was blissfully unaware. Other than that, can you name any?Love is always a difficult prospect for a woman in stories. The Hallmark Channel has made it into big business, especially at the holidays. Young Adult Lit is littered with it. It's compelling until it's not. It's the stuff that soap operas are made of--that and evil twins back from the grave.As I said before, I don't hate love triangles, but there are times they feel manipulative. Hans Christian Andersen had the right idea about them, but that ended in death (or dissolution depending on your point of view).That felt selfless and brave.Most love triangles are petty and usually involve a woman toying with the affections of two people. And that just toys with the audience's emotions and not in a good way.Okay, end of rant.How about you? How do you feel about love triangles? And plot devices that make you go on a rant?
