I learned about this word recently, too. Lowering the barrier for the curious- From Wikipedia: Psychologist Dorothy Tennov coined the term "limerence" for her 1979 book, Love and Limerence: The Experience of Being in Love, to describe a concept that had grown out of her work in the mid-1960s, when she interviewed over 500 people on the topic of love.[1] Limerence, which is not exclusively sexual, has been defined in terms of its potentially inspirational effects and relation to attachment theory. It has been described as being "an involuntary potentially inspiring state of adoration and attachment to a limerent object (LO) involving intrusive and obsessive thoughts, feelings and behaviors from euphoria to despair, contingent on perceived emotional reciprocation". https://en.m.wikipedia.org/wiki/Limerence https://en.m.wikipedia.org/wiki/Limerence
