It's not a mistake... These days the kind of guts some men have in cheating, it's out of this world. A chest will always find a reason to cheat.
The painful part is society accept a man to cheat, many women Marry them because they are pressured to manage him..
They tell her it doesn't matter as far as he marries you, so she has no choice. She hardly see someone that can tell her she deserves more than cheat!
