Events of L.A. Noire
Due to the stress and trauma of his experiences during the war, Cole had been emotionally and mentally damaged. It is never openly stated, but strongly implied that he became emotionally distant from his wife and daughters. Instead of them, he focused primarily on his detective work, which constituted his personal quest for redemption. Cole eventually developed a love interest in a German singer, Elsa Lichtmann, and the two began an affair.
Marie learned of this affair after anonymously receiving a set of photographs exposing Cole and Elsa's intimacy, greatly appalling Marie and upsetting their two daughters. With the affair public, Marie formally charged Cole with adultery, disgracing him, and later causing his demotion from Vice to Arson. Marie was angered and betrayed by Cole because of his affair and humiliated from being stalked by reporters and press. Cole returned home, attempting to explain himself. However, Marie refused to listen or let him see the girls; she simply threw out his belongings. To make matters worse, Cole could not even deny being in love with Elsa. Despite this, after Cole's death, Marie and her two daughters attended his funeral.
