In Macbeth, how does Macbeth respond to the English attack and the death of his wife?

In Macbeth, Macbeth has made a false
interpretation of the witches' prophecy and this causes him to believe that he is nearly
invincible in the face of attack.  When Macbeth learns that the English army is
advancing on his castle, he is not overly afraid because he thinks that "no man of woman
born" can harm him.  Macbeth does not see how anyone could not be of "woman born," so he
thinks that no one can hurt him.  As a result, he vows to fight.  When Lady Macbeth
commits suicide, Macbeth does not stop to mourn her death and says that there is no time
for such things.  He says that she was bound to die sooner or later, so to him, her
death is no great tragedy.  However, even though Macbeth does not react strongly to
these individual events, he is aware that he has lost much because he has not ruled
well--a bit earlier in the play, Macbeth acknowledges that he will not grow old with
respect, love, loyalty, and friendship the way good kings do.
