I don't understand people being in open relationships where they are not monogamous.  Why even BE in a relationship?
An open relationship is an intimate relationship which is consensually non-monogamous.

Open relationship
An open relationship is an intimate relationship which is consensually non-monogamous. This term may sometimes refer to polyamory, but it is often used to signify a primary emotional and intimate relationship between two partners who agree to have sexual relationships but not romantic relationships with other people. The nature of the openness in the relationship, including what outside sexual contact is permissible, varies widely. Open relationships include any type of romantic relationship (dating, marriage, etc.) that is open. The concept of an open relationship has been recognized since the 1970s.
Open marriage relationship
Relationship maintenance comprises behaviors partners perform in order to maintain satisfaction and extend the duration of a relationship. The impact of open marriage on relationships varies across couples, yielding positive, neutral, and negative outcomes. Some couples report high levels of marital satisfaction and have long-lasting open marriages. Other couples drop out of the open marriage lifestyle and return to sexual monogamy. Still other couples experience serious problems and report that open marriage contributed to their divorces. Scientists do not yet understand why some couples respond positively to open marriage while other couples respond negatively.
Monogamy
Monogamy ( ) is a form of relationship in which an individual has only one partner during their lifetime or at any one time (serial monogamy), as compared to polygamy, polyandry, or polyamory. The term is also applied to the social behavior of some animals, referring to the state of having only one mate at any one time. The term monogamy is used to describe for different relationships. Biologists, biological anthropologists, and behavioral ecologists often use the term monogamy in the sense of sexual, if not genetic, monogamy. Modern biological researchers, using the theory of evolution, approach human monogamy as the same in human and non-human animal species.
Polyamory
Polyamory (from Greek ', "many, several", and Latin ', "love") is the practice of, or desire for, intimate relationships with more than one partner, with the knowledge of all partners. It has been described as "consensual, ethical, and responsible non-monogamy". People who identify as polyamorous reject the view that sexual and relational exclusivity are necessary for deep, committed, long-term loving relationships. Polyamorous arrangements are varied, reflecting the choices and philosophies of the individuals involved, but with recurring themes or values, such as love, intimacy, honesty, integrity, equality, communication, and commitment.
Open marriage jealousy
Open marriage jealousy refers to thoughts, feelings, and behaviors associated with romantic rivalry and jealousy within an open marriage. Couples in open marriage expose themselves to situations that can potentially provoke jealousy. Most couples in open marriages report experiencing jealousy at some point during their marriage. Couples in open marriages also experience jealousy more frequently than couples in sexually monogamous marriages. Ground rules are one way to help manage jealousy in open relationships. However, ground rules may not be sufficient. Couples in open marriages may benefit from a general understanding of jealousy and how to cope with it.
Infidelity
Infidelity (synonyms include: cheating, adultery (when married), netorare (NTR), being unfaithful, or having an affair) is a violation of a couple's assumed or stated contract regarding emotional and/or sexual exclusivity. Other scholars define infidelity as a violation according to the subjective feeling that one's partner has violated a set of rules or relationship norms; this violation results in feelings of sexual jealousy and rivalry. What constitutes an act of infidelity depends upon the exclusivity expectations within the relationship. In marital relationships, exclusivity expectations are commonly assumed although they are not always met.
Open marriage incidence
The incidence of open marriage is the frequency with which open marriage occurs. Several definitional issues complicate attempts to determine the incidence of open marriage. People sometimes claim to have open marriages when their spouses would not agree. Couples may agree to allow extramarital sex but never actually engage in extramarital sex. Some researchers define open marriages in narrower terms than others. Despite these difficulties, researchers have estimated that between 1.7 percent and 6 percent of married people are involved in open marriages. The incidence of open marriage has remained relatively stable over the last two generations.

That is a great question.  To me, an "open" relationship sounds more like "no" relationship.  What say you?
