Found this while surfing looking about MLC and OW.
It was about Affair Down during MLC: There is nothing special about her other than that she gives him her attention and admiration--those are not to be underestimated. She fulfills his need for validation. An OW must be willing to date a married man. She may not seem willing in that she pressures him to leave and divorce you, but she was willing to start a relationship before he fulfilled that requirement.
Strong people who value themselves do not allow themselves to become involved with people who are married. MLCer OWs are desperate woman seeking a rescuer to save them from their sorry lives. They will thus do whatever it takes to get this man who has shown a history of commitment through his marriage--thus he is a better catch than a man who is available. She auditions for the role of perfect fantasy wife by listening to his problems and soothing his wounded ego. She is attentive not only sexually but also and more importantly, emotionally.
OWs allow their desperation to cloud their judgment. She is so desperate that she justifies his mistreatment of you and believes he will never mistreat her also. He did not choose the OW because she is better than you or because you failed. He chose her because she was willing.
