When my daughters were teens I told them to be particularly aware of three traits in a boy because these traits influence what kind of man he would become.

Points to build on

1. How does he treat his parents?

Proverbs 19:26  "He who mistreats his father and chases away his mother is a son who causes shame and brings reproach."

Proverbs 28:24  "Whoever robs his father or his mother, And says, 'It is no transgression,' The same is companion to a destroyer."

Proverbs 30:17  "They eye that mocks his father, And scorns obedience to his mother, The ravens of the valley will pick it out, And the young eagles will eat it."

2. Is he cruel to animals?

Proverbs 12:10  "The righteous man regards the life of his animal, but the tender mercies of the wicked are cruel."

3. How does he treat those whom he sees as weaker than himself?

Proverbs 14:31  "He who oppresses the poor reproaches his Maker, But he who honors Him has mercy on the needy."

Application

These principles apply to any woman looking for a good husband.  No matter how attractive, charming or rich a man may be, if he mistreats his parents; is cruel to animals; and oppresses those who he sees as weak he will do the same to his wife and children.
