I’ve read a quite interesting article about husband cheating his wife..the DNA test can indentify the possibility of a man could cheating his wife if he have some kind of alele in their DNA..for me that’s something cool..but basically women can discover when their husband is cheating them by just looking at their husband behavior..women could sense it when their husband change his behavior like suddenly change their appearence like never before..asking their wife to spend time more with their friend(just to name few)..that is some bad sign..should act before its too late..
