What is the main conflict in My Life with the Wave by Octavio Paz?

In "My Life with the Wave," a man, while at the beach, is seduced by an ocean wave, which insists on following him home to Mexico City. The man and the wave have a passionate, turbulent, love affair, in which the wave is both adoring and demanding. Because she is lonely, he brings her a school of fish to swim in her waters; but, when he becomes enraged with jealousy of her attentions to the fish, he tries to attack them, and the wave nearly drowns him. After that, his love for the wave turns to "fear and hate." To get away from her, he leaves home for a month. When he returns, he finds that the winter weather has turned the wave into "a statue of ice." With cold malice, he sells the frozen wave to a friend of his, a waiter at a restaurant, who chops the ice into small pieces to be used for cooling drinks.
