The term is used frequently in psychology, popular writing, and journalism. It can be applied to relationships with inanimate objects, or even concepts, as well as those of a romantic nature or between siblings and parents/children.
A love–hate relationship has been linked to the occurrence of emotional ambivalence in early childhood; to conflicting responses by different ego states within the same person; or to the inevitable co-existence of egoistic conflicts with the object of love.
Narcissists have been seen as particularly prone to aggressive reactions towards love objects, not least when issues of self-identity are involved: in extreme instances, hate at the very existence of the other may be the only emotion felt, until love breaks through behind it.
The term is sometimes employed by writers to refer to relationships between celebrity couples who have been divorced, then who reunite (notably Elizabeth Taylor and Richard Burton, or Eminem and Kimberly Scott), as well as to their relationship with fame itself.
A love–hate relationship may develop when people have completely lost the intimacy within a loving relationship, yet still retain some passion for, or perhaps some commitment to, each other, before degenerating into a hate–love relationship leading to divorce.
Tony Blair and Gordon Brown's political friendship took on at times all the characteristics of a love–hate relationship, if one between friends and allies. Sigmund Freud said of himself that “an intimate friend and a hated enemy have always been indispensable to my emotional life...not infrequently…friend and enemy have coincided in the same person”.
- The Japanese word "tsundere" comes from two words—tsuntsun (aloof, irritable, cold) and deredere (lovestruck). A tsundere character is one who frequently switches between insulting their love interest and acting lovestruck or kind toward them. Tsundere characters usually belittle their love interest at first but eventually become kinder to them over time.
- Catullus introduced the love–hate theme into Western culture with his famous lines: "I hate and yet love. You may wonder how I manage it. I don't know, but feel it happen, and am in torment".
- The concept of a love–hate relationship is frequently used in teen romance novels where two characters are shown to "hate" each other, but show some sort of affection or attraction towards each other at certain points of the story.
