it makes it somehow feel better to know there are other good people out there who have done stupid things.
Whoa! Stop right there! Someone put up a comment about nuns and not feeling guilty. That post is VERY IMPORTANT. Read it several times.
Did you know at the time you had your affair what you know now? No. Did you realize the damage you were doing? No. Were you in an emotional state to even understand the consequences if you heard them? No. You were essentially ignorant. There may be plenty of reason why you were ignorant, but that is not reason to feel guilty. The ONLY reason your should ever feel guilty is if you KNEW full well what you were doing was wrong, why it was wrong and all the consequences of your action, and you CONSCIOUSLY decided to do it anyway. What you did was not stupid, only ignorant. Don’t go down that road.
