An Open Relationship is a committed partnership in which both people agree they can have sexual or romantic connections with others.
An open relationship is a form of consensual non-monogamy where partners agree that one or both of them can see other people. The core relationship stays central, but it is not sexually exclusive.
It differs from cheating in one essential way, which is consent. Everything happens with the knowledge and agreement of the partner, not behind their back.
Open relationships run on rules the couple sets together. What is allowed, what is off limits, what gets shared, and how to protect each other’s health and feelings.
It also differs from polyamory, which centers on multiple loving relationships. Open relationships are often more focused on sexual freedom while keeping one emotional partnership primary.
The foundation is communication and honesty. These arrangements tend to work when partners are secure, talk openly about jealousy, and revisit the rules as needed.
They are not a fix for an unhappy relationship. Opening up usually works best from a place of existing trust rather than as a last resort.
