Men and women get jealous over different things. A man tends to be jealous of other men in his wife's circle, while a wife is jealous of the activities themselves which make him spend time away from her. A wife wants to be her husband's number one priority. When the husband spends a lot time away from her, she feels unwanted and unloved. Women expect men to share and do household chores without being asked.
Men often take the attitude that they are helping the wife out when they pitch in - doing a favour.
In fact most women need to feel emotionally intimate before physical intimacy. The same is not true for men. Women consider a gift's meaning and look for the message behind a particular gift. A gift may say that 'I want to please you' or 'I am not really bothered about you'. Men prefer that women should tell them what they want while women prefer that men should understand what they want.
