What is the main conflict in The Rainbow by D. H. Lawrence?

The Rainbow chronicles three generations of Brangwens living near Marsh Farm. Sexually stormy marriages set the stage for conflict and power struggles within the home. Tradition, passion, children, and compromise define the Brangwen clan, giving its members both happiness and sadness. Ursula Brangwen, the granddaughter of the original Brangwens, takes on the pressures of her upbringing in order to experience life and love on her own terms.
