Describe the relationship between Macbeth and lady Macbeth.how is the difference betwen them
From the beginning, Macbeth hears from the witches his prophesy and wishes to one day to become king. When King Duncan announces that his son Malcolm will become king next, Macbeth sees him as an obstacle. He begins thinking of how he can over take the throne. So he gets his wife thinking along the same lines in his letter to her. Their relationship is close at this point.
Lady Macbeth is immediately ambitious. Macbeth had to think it through, though. He knew he should remain loyal to Duncan, but he wanted the crown, too. He went back and forth with the idea of murder. Lady Macbeth jumped at the opportunity and convinced her husband (through challenging his masculinity) to kill Duncan while he was in her house. At this point, husband and wife are not on the same page. She is completely into committing this murder. Macbeth keeps going back and forth with the idea.
After Duncan's sons flee, Macbeth is crowned and he makes a change. He looks to Banquo and his son as a threat. Lady Macbeth is no longer in on the schemes. He doesn't tell her about his murderous plans of Banquo and Fleance, or even of killing Macduff's family. She is all alone with her guilt and slowly goes crazy with it.
By the final Act, Lady Macbeth is completely lost mentally and gets no help from Macbeth. He is so caught up in his plans that he has a doctor take care of her for him. So by the end, they are so far apart, she dies and he continues his plotting.
