If your mistress turned against you, how would you feel?

You started an affair with a woman while you were alone and based in another country. After 16 months, you ended the affair and went back to the wife and kid. However, the mistress got angry and demanded that you and your wife (who found out about the affair later) apologise to her for her trauma and heartaches. The mistress was angry that your wife scolded her for seducing her husband which was true. The last straw was when the mistress email photos of you semi-nude to the office and your boss to embarre you. Guys, how would you feel and react in this kind of situation? Angry? Remoseful? Guilty?
