What is משולש אהבה?

Not necessarily. A love triangle is a plot structure about competing attractions; whether cheating occurs depends on the characters’ actions and the story’s moral framing. Many stories use triangles without infidelity—choices can happen before any duties are broken.

Give each character distinct, believable motivations; avoid making one suitor a perfect prize and the other a villain. Let the protagonist grow through the conflict, and explore emotional consequences honestly. Subvert expectations by changing who has agency or by offering non-binary resolutions.

It can, but the terms are different. A traditional ‘love triangle’ implies tension and usually a choice; consensual polyamory is a mutually agreed arrangement without a single choice. If portraying polyamory, center communication and consent rather than rivalry.
