I don't want to generalize in this manner. Nowadays, there is a lot of jealousy among men also, and many women are able to handle many situations very even mindedly, and are able to let-go easily. May be it is because women are more emotional and since jealousy is an emotion, they experience more of this.
On the other hand men are generally more intellect centric and and therefore experience this emotion a little less. But this is not necessarily the rule.
You must be reading in the newspapers daily. What all horrific crimes boys do out of jealousy.
