What is known as revolving door marriages. When is it okay? Some say abuse or adultery, but they also remarry. I've always been told to remove oneself from the situation and seek counseling, but not to divorce. Lord Jesus said divorce was allowed (not ordered or expected) for the hardness of human hearts: (Matthew 19:8). He taught that man ought not to put a marriage asunder because his ideal is one man, one woman as an Inseparable unity (Matthew 19:6). God spoke of how he hates putting away (divorce) (Malachi 2:16). The Apostle Paul stresses that if you do harden your heart and separate and/or divorce, then you must either remain unmarried or be reconciled as the only two Biblical options (I Corinthians 7:1011). Also, Paul stresses the law of God as our authority in this matter and that as long as our spouse lives, marriage is intact, no matter what men may say or do (I Corinthians 7:39, Romans 7:1-3). I knew a lady who was married for 21 years when she discovered her husband was a "homosexual" or so he thought. She didn't tolerate his behavior and moved out, they both sought counseling and are still together today.
