Why are all boys deceptive and only care about playing with girls' feelings?

The judgment that young men are generally not righteous is a mistake, for there is still good within the Ummah and many virtuous youths. Whoever rectifies himself and fears his Lord, Allah will bless him with a spouse of similar virtue, for Allah says: "And the good women are for the good men, and the good men are for the good women." It is advised to fear Allah and to beware of emotional relationships, premarital acquaintances, and speaking with non-mahram (definition) individuals, due to the prohibitions and temptations therein.
