What changes do you notice in macbeths character and in the relationship between macbeth and his wife?

Macbeth and his wife are not getting along. She's power hungry; she wants more and more.... she is not satisfied. Macbeth, on the other hand, is living with a lot more guilt than he bargained for...... he simply wants the woman to be QUIET! The two put on false faces in order to keep up public appearances...... and Lady Macbeth is ever putting forth suggestions for further evils. They're a disaster.
