why Men are Egoistic and Women are Jealous ?

Welcome to myLot spacehunter! Do you have any statistical evidence for your statement, or is this your observation? I might tend to agree that a lot of men are egotistic, but I don't think a blanket statement can be made. Besides, a lot of women are too. I'd certainly be prepared to think that men of previous generations were somewhat egotistical, because the responsibilities (and superiority) of manhood were drummed into them - "Boys don't cry! Be a MAN!" type of thing. At that time girls were taught they were little more than a decoration and their role was to please their man. Jealousy. Are women more jealous than men? Well, women are more emotional, so it is possible, but men have been driven to murder over jealousy, so women don't have a monopoly on jealousy. I really don't think men or women have specific claim to any feeling, emotion or status, though I do still believe the role of the man is the head of the house: the strong one who protects his family. I still believe the woman should be the soft and feminine, motherly type who comforts and provides emotional stability for the family - but that idea will bring the fury of women's libbers, I'm afraid.
