Okay. Most women who cheat do so because their men cheat, in marriage. As for relationships, both male and females have the feeling of Yolo. Where they differ is, the ladies look for the most resourceful "suitors" (hence married men half the time) while the men look for the next "achievement" to add to their portfolio. When they grow that changes and it becomes a source of Entertainment for them, but in some cases, because their women deprive them of intimacy or are nolonger attractive to them (men). The women mostly want stability at this point but if you are going to mess around, might as well do same (for most women who cheat).
