In the novel Like Water for Chocolate, Laura Esquivel defines love in so many different characteristics. Specifically, the love between Tita and Pedro was expressed in so many different ways. Obsession, jealousy and sacrifice were defined as love between Pedro and Tita.
The American Heritage Dictionary defines obsession as a compulsive, often unreasonable idea or emotion. This was one of the ways that love was defined. An example of this was the obsession that Tita and Pedro had together. But, at the beginning of the novel we find out that Pedro is obsessed with Tita. He wanted to do nothing more than to spend the rest of his life with Tita, unfortunately this was impossible. Tita, according to family tradition, being the youngest daughter was not allowed to marry and is forced to take care of her mother. This drove Pedro's obsession for Tita even further. Pedro goes to the farm twice to ask Mama Elena for Tita's hand in marriage but both times he is denied. Though on his second attempt Mama Elena suggests Tita's sister, Rosaura. Pedro accepts the marriage invitation to Rosaura. But, Pedro only does this to get closer to Tita, his true love. "Why did you do that, Pedro? It will look ridiculous, your agreeing to marry Rosaura. What happened to the eternal love you swore to Tita? Aren't you going to keep that vow?" "Of course I"ll keep it. When you"re told there's no way you can marry the woman you love and your only hope of being near her is to marry her sister, wouldn't you do the same?" P. 15 This dialogue between Pedro and his father is crucial to his obsession that he had for Tita. He was willing to risk getting married to someone he did not love, only to be closer to his true love. But with Pedro's obsession with Tita strong, it might have had the opposite effect: jealousy.
Jealousy is defined as "close vigilance", by the American Heritage Dictionary and in the middle of the novel; a couple of months after Pedro and Rosaura's marriage, Pedro had a close vigilance with Tita's new male companion.
