Cheaters Never Win!

This is my favorite trope by far when a spouse/partner who does not appreciate his partner strays and becomes cold with them maybe even requesting a divorce.  But in the end, karma always wins.  The cheater regrets their dalliances and/or tries to get back what they through away to no avail.  The innocent partner walks off into the sunset either content with themselves or preferably with someone WAY HOTTER and RICHER than the cheater.
