In my experience with most people (unfortunately), given the chance, they can rationalize almost any transgression on their part and infidelity is definitely one of them. My ex-wife has NEVER apologized for her 3 affairs. It used to bother me tremendously, fortunately now I could care less and it is so nice to be past that point. My father was horribly unfaithful to my mother and to this day he has never once apologized for it and owned up to it.
Sadly, it seems to be the exception when someone is unfaithful that they admit their mistakes - it always seems to be some characteristic fault of the spouse/significant other that caused them to be unfaithful.
