In polyamory, a metamour is your partner’s partner—the person you’re connected to through shared love, but not necessarily romance. While you may never become best friends (or even directly close), building a respectful, healthy dynamic with your metamour can make everyone’s relationships smoother, happier, and less stressful.
Metamour relationships don’t need to be perfect, but they thrive on mutual respect, patience, and empathy. By practicing good etiquette, you can create an environment where everyone feels valued—and where your shared partner doesn’t feel torn between people they love.
