In Singapore, a young bride had to go to court to force her husband stop letting his mother sleep under their bed.
Genesis in the Bible records the plan of God for mankind to marry; a man is to leave his father and mother and be joined to his wife and they will become one flesh. He didnt say they should be joined to each other until they lost interest in each other. Or until one partner felt trapped by the confines of the relationship and wanted out. Or until a child complicated the scene. He said they should be joined to each other and become one. That process takes a lifetime.
