OK OK Men cheat and women cheat period: the reason men get caught more often is because they are not as smooth as women when they are cheating.
This question is actually not that easy to answer, because different women have diff view of what cheating is, for some women for a men to look at an other woman will be cheating. But I can tell you that to some man cheating is just an endorphin to boots their status, ego and so on, and men rarely see the side effect until it's too late i.e breaking up their family, losing the affection, support and family love, just for some simple thrill.
If you want to keep you man you have to be open minded and spontaneous.
In a relationship 9 out of 10 it seems that the man end up taking an interest in something his girlfriend like. Ladies I will recommend you do the same take interest in something the person love, if it is sports instead of arguing about what channel it should be on take an interest in the sport. This is sure to solve something and since male love to be in charge he will be more than happy to tell you how the sport is play, he will love to educate you on what a first down is.
