Ask another priest, your husband knew what he was doing. I’m assuming he knows right from wrong! He knows not to rob a bank or drive drunk, correct? Your husband made the choice to cheat. My husband blamed his 2 year on going affair on prostate cancer treatment, his father being Ill and Parkinson’s for his cheating, but he still knew the difference between right and wrong. Cheating is a choice, as everything else in life.
