What is a friendship that hates and appreciates each other?

This is a "friend-enemy" relationship. Studies show that from adolescence, there will be fewer and fewer pure friends and enemies, and a new type of relationship called "friend-enemy" will become more and more, and even become a social role that adults often face or play in the world.

Holt-Lunstad(2007), a scholar who studies the relationship between friends and enemies, believes that if this relationship is also classified as friendship, it accounts for more than half of adult friendship, that is to say, in adult social relations, "friend-enemy" relationship is more common than pure friendship.

Speaking of "friends and enemies", many adolescent drama stories and fragments from American TV series Sex and the City and Gossip Girl come to mind.

Frenemies, usually called "contradictory network ties", was first put forward in 1953 to describe the relationship between the United States and the former Soviet Union at that time, which combined the characteristics of friends and enemies. Nowadays, we will use this word to describe all kinds of complex relationships between countries, enterprises/institutions and individuals.

The word "friend or enemy" was included in the Oxford Dictionary in 2008. It is defined as "a seemingly friendly relationship despite dislike or hostility". Urban Dictionary defines it as: "People who are both friends and enemies, your relationship is mutually beneficial or interdependent, competitive, full of danger and distrust."

If happiness, love, support and care are all positive parts of interpersonal relationships, then unreliability, depression and demanding are all negative parts.

We are usually regarded as friends and enemies, which is a contradictory interpersonal bond. It not only provides us with some support and care, but also makes us feel depressed, unhappy and competitive.

Friends and enemies are more common in women's friendship than men, especially in adolescent women's friendship. This may be related to the fact that women are more likely to be taught to be "good-natured" and "not to be aggressive and competitive in public". At the same time, the relationship between friends and enemies may be unilateral, for example, one party regards the other as friends and enemies, and the other party does not know it.
