Pathetic characters
lost in their marriages, raising kids, their social lives--lives without much passion--cheating and falling in love as an escape. But still I was rooting for them despite my brain reminding me it was adultery and was done without regard for their respective spouses' feelings (if they'd found out). Love, sex, and secrecy, a powerful combination.
They knew it was wrong and they did it anyway, not apparently considering the path of divorce as a potential solution.
