People have different emotional reactions toward different target persons in the context of romantic love and hate. Our study revealed a complex picture of love and hate. Additionally, stronger feelings of love were associated with greater hate after the relationship was broken, suggesting a link between romantic love and hate.

The results showed that people who shared similar values and interests with the target persons were more likely to experience stronger love. The present study investigated whether similarity within romantic partners was associated with greater feelings of love in the absence of betrayal, and greater hate induced in the presence of betrayal by using vignettes to induce love and hate in a sample of 59 young adults. However, few studies have been conducted on the relationship between love and hate. Previous research has focused on the classification, functions, and other aspects of these two affects. 4Cognition and Human Behavior Key Laboratory of Hunan, Department of Psychology, Hunan Normal University, Changsha, China.
