:salamext:
'Umar radhiAllaahu anhu was a person who was rough in his lifestyle, and he was a zaahid (someone who isn't attatched to this world.) And because the women knew that he was like this, they were afraid that they would have to live this sort of lifestyle too - if they were to marry him.
So they backed away due to that.
Just think about it, does a woman want to live a poor life? No. She want's to feel secure and have a comfortable life. This just wasn't the personality of 'Umar radhiAllaahu anhu, because he preferred the afterlife over this world. And he was of the 10 promised paradise, he obeyed the Messenger of Allaah (peace be upon him) who said:
The Messenger of Allaah (peace be upon him) said: "The best among you is the one who is best to his wife" (Related by Ibn Hibban) in another version it is the one who is most kind to his wife.
Now look at this:
It is reported that a man came to 'Umar ibn Al-Khattab raa to complain about his wife's ill-temper. While he was waiting for 'Umar to come out of his house, he heard 'Umar's wife scolding him and 'Umar quietly listening to her, and not answering her back. The man turned around and started walking away, muttering to himself: "If that is the case with 'Umar, the leader of the believers, who is famous for his uprighteness and toughness, then what about poor me?!" At that moment, 'Umar came out of his house and saw the man walking away. He called him and said, "What is it you want of me, O man?" The man replied: "O leader of the believers, I came to complain to you about my wife's bad-temper and how she nags me. Then I heard your wife doing the same to you, so I turned around, muttering to myself, 'If that is the situation of the leader of the believers, then what about me?'" 'Umar replied, "O my brother, I bear with her because of her rights over me. She cooks my food, bakes my bread, washes my clothes, breast-feeds my child...and yet none of these are her duty;
* and then she is a comfort to my heart and keeps me away from forbidden deeds. Consequently, I bear with her." The man said, "It is the same with me, O leader of the believers." 'Umar said: "Then, O my brother, be patient with her, indeed this life is short. (Adh-Dhahabi,
