“Whoever divorces his wife and marries another commits adultery against her, and if ever a woman after divorcing her husband marries another, she commits adultery.”
Mark 10:11,12

Jesus added the exception that a divorce can be legitimate before God if the betrayed spouse files “on the grounds of sexual immorality.” (Matt. 5:32; 19:9)
In Jesus’ day, Jewish culture did not allow women to file for divorce.
If a man cheated on his wife, he was not considered an adulterer.
A woman who cheated on her husband was an adulteress, and the man whom she sinned with would be committing adultery against her husband.
But they did not consider it possible for a man to commit adultery against his wife. (Watchtower July 15, 1995, pp. 18-19, parr. 12-13. “Christian Women Deserve Honor and Respect.”)
With his statement on God’s view of marriage, Jesus pressed his followers to rid themselves of the double standard.
By using the example of a woman who “divorces her husband,” he was dignifying women, giving them that freedom of choice.
Many traditional cultures today still urge female victims of adultery to overlook their husband’s infidelity.
Sometimes their friends and family will excuse the male’s behavior by saying that it is typical in all men, arguing they did not really hurt anyone.
When a social circle does that to a victim, they are isolating her and taking away her will power to do what is right in her heart.
They may go so far as to shame her instead of the culprit, blaming her for his moral fallout.
As true Christians, we must learn to react to others’ suffering the way Christ did: with sensibility and respect, putting their needs before our own expectations.
