Do I have to end a love triangle story?

Not always. You could keep the love triangle going if it serves a greater purpose in your plot, like building tension or exploring different aspects of love and relationships. But be careful not to drag it on for too long.

It really depends. You could end it with a clear choice by one of the characters, or maybe leave it open-ended for the readers to imagine. The ending should fit the tone and themes of your overall story.

Often, one person makes a choice. For example, in some stories, the female lead chooses the guy who she realizes truly loves her and has her best interests at heart.

Often, one person in the triangle is left heartbroken. For example, in 'Romeo and Juliet', Paris is left out as Romeo and Juliet pursue their love and ultimately die together. In some cases, the main character realizes who they truly love and choose that person. Like in 'Pride and Prejudice' Elizabeth chooses Darcy in the end.

One way could be to have one of the characters voluntarily step aside and find love elsewhere, allowing the remaining two to be together.

Often, they end with a resolution of some sort. For example, in 'Pride and Prejudice', Elizabeth and Mr. Darcy end up together, while Mr. Wickham is sort of pushed out of the picture. The good - hearted characters usually get their happy endings, while those with bad intentions or who are obstacles in the relationship don't fare as well.

Often, one person in the love triangle ends up with the main character they are meant to be with. For example, in 'Inuyasha', Inuyasha finally chooses Kagome over Kikyo. Another way is that the character in the middle realizes they don't have romantic feelings for either of the other two in the triangle and decides to be alone or just be friends, like in some less - common storylines.

They often end with one person making a choice. For example, the person at the center of the triangle decides to be with one of the suitors. Or it could end with all parties realizing it's too complicated and walking away.

Often, the protagonist makes a clear choice between the two love interests. For example, in some novels, the girl might realize that one guy has been there for her all along and truly understands her, so she chooses him over the other.

They can end with one person making a selfless choice. For example, one of the people in the triangle realizes that their friend really loves the person more and steps aside. Another way is that the person who is the center of the triangle chooses one of the two. Sometimes it's a happy ending where the couple stays together, and the other person moves on.
