Love-ins, which refers to public displays of affection and romantic expressions, can have a plethora of antonyms dependant on context. In the context of an abusive or toxic relationship, antonyms could include hostility, disdain, or resentment. In a more general context, antonyms for love-ins could include indifference, apathy, coolness, or reserve. These words reflect a disinterest in engaging in public displays of affection or a lack of romantic expression. However, it is important to note that while love-ins may not be for everyone, healthy relationships still involve acts of love and care, whether they are overt or subtle.
