ELI5: Explain Like I'm 5

Non-monogamy

Non-monogamy means that you can have more than one romantic relationship at the same time. This means that instead of just being with one person, you can be with two or more people who all love each other. It can mean being in an open relationship with people you know and like, or being in a polyamorous relationship where you have a few different partners. Everyone who is part of the relationship should be honest and respectful of each other, and should talk about how to make sure everyone involved is happy.
