Divorce

God hates divorce

Another thing you do: You flood the LORD’s altar with tears. You weep and wail because he no longer pays attention to your offerings or accepts them with pleasure from your hands. You ask, “Why?” It is because the LORD is acting as the witness between you and the wife of your youth, because you have broken faith with her, though she is your partner, the wife of your marriage covenant. Has not the LORD made them one? In flesh and spirit they are his. And why one? Because he was seeking godly offspring. So guard yourself in your spirit, and do not break faith with the wife of your youth. “I hate divorce,” says the LORD God of Israel, “and I hate a man’s covering himself with violence as well as with his garment,” says the LORD Almighty. So guard yourself in your spirit, and do not break faith. - Malachi 2:13-16 NIV

Separation should not be sought (Matthew 19:6, Mark 10:9)

To the married I give this command (not I, but the Lord): A wife must not separate from her husband. But if she does, she must remain unmarried or else be reconciled to her husband. And a husband must not divorce his wife. - 1 Corinthians 7:10-11 NIV

Is allowed by Jesus for adultery (due to hardness of heart not allowing reconciliation to happen. Note: Reconciliation is still the goal as the covenant is still in place)

“It has been said, ‘Anyone who divorces his wife must give her a certificate of divorce.’ But I tell you that anyone who divorces his wife, except for marital unfaithfulness, causes her to become an adulteress, and anyone who marries the divorced woman commits adultery. - Matthew 5:31-32 NIV

I tell you that anyone who divorces his wife, except for marital unfaithfulness, and marries another woman commits adultery.” - Matthew 19:9 NIV

Is recognised to happen to believers by unbelievers due to their Christian commitment.

But if the unbeliever leaves, let him do so. A believing man or woman is not bound in such circumstances; God has called us to live in peace. - 1 Corinthians 7:15 NIV (Note: "bound" is the Greek "Douloo" - as in bondage as slave, servant or bondman...)
