An extramarital affair that continues in one form or another for years, even as one of the partners to that affair passes through marriage, divorce and remarriage, could be considered the primary relationship and the marriages secondary to it. Several people claim the reason of extra marital affair as their unsuccessful marriage and that both spouses failed to please each other. This may be serial polygamy or other forms of nonmonogamy.Extramarital affairs are relationships outside of marriage where an illicit romantic or sexual relationship or a romantic friendship or passionate attachment occurs.
The ability to pursue serial and clandestine extramarital affairs while safeguarding other secrets and conflict of interest inherent in the practice, requires skill in deception and duplicitous negotiation. Even to hide one affair requires a degree of skill or malicious gaslighting. All these behaviors are more usually called lying.
