Extramarital affairs are relationships outside of
marriage where an illicit
romantic or
sexual relationship or a
romantic friendship or
passionate attachment occurs. An affair can continue in one form or another for years, even as one of the partners in that affair passes through marriage, divorce, and remarriage. This could be considered the primary relationship, with the marriage secondary to it. Several people claim the reason for an extramarital affair is their unsuccessful marriage where both spouses fail to please each other. Dissatisfaction, low self-esteem, desire for adventure, and impulse are also major motivating factors of romantic affairs. This may be serial polygamy or other
forms of nonmonogamy. Individuals having affairs with married men or women can be prosecuted for adultery in some jurisdictions and can be sued by the jilted spouses in others, or named as 'co-respondents' in divorce proceedings. As of 2009, eight U.S. states permitted such
alienation of affections lawsuits. Affairs with the consent of their significant others may not be considered infidelity or adultery. ==See also==
