Yes I've experienced it. Probably still am. I'm not sure I'm clear of it but am ruthlessly no contact.
Is it not another term for a crush?
No. A crush is less invasive and more short lived. If a crush is, say an 8 on a scale of 1 to 10 of excessively loving feelings, limerence is off the scale, has broken the dial and is probably rocking in at around a score of 100.
Limerence is an overwhelming obsession. It's really unpleasant -because it only survives in a climate of limited reciprocation. It's almost psychotic. The feelings are huge but utterly irrational.
Features include things like:
- massively intrusive thinking - ie. you can't concentrate on anything other than the limerent obejct.
- prefering to spend time fantasising about the limerent object than doing anything else.
- feeling almost high when in the presence of the limerent object and immediately afterwards.
- excessive analysis about interactions with the limerent object
-feeling like the limerent object is utterly perfect, almost god/goddess like.
A key feature in prolonging limerence is mixed signals. It doesn't last if you actually spend a lot of time with someone, it wears off. Here is a quote from the first article below.
What's the trick? "Their feelings were unrequited," she reports. "Their LOs gave them mixed signals, like ignoring them for months and then calling. Hope, confusion, and uncertainty kept it going. The phenomenon is defined, in part, by feeling a loss of control. The limerent person can't stop thinking about the LO: What did he mean by that? How can I interpret his tone of voice? How is he responding to me? A prolonged fixation on someone who doesn't love you back is considered, by some psychologists, a pathology called erotomania."
^"If the LO is responsive," Tennov says, "like your boyfriend, he doesn't send mixed signals, you don't experience uncertainty, the love is mutual, and limerence declines. Unless you want to start pretending you don't have feelings for him, or playing hard to get, the end will come." Discouraging news.
And then some hope: "Barriers and hurdles in the relationship lengthen infatuation," Fisher says. "For example, suppose one of you is married. Or one lives in a different city. The struggle is romantic. You say your boyfriend travels a lot for work? That's good. The pain of his leaving and the happiness of his return can prolong the stage."^
