Signs of "limerence" (infatuation)
1. Intrusive thinking (can't stop thinking about LO)
2. Acute longing for reciprocation (wanting LO to love back)
3. Dependency of mood on LO's actions or interpretation of LO's actions (e.g. interpreting actions as indicating reciprocated love)
4. Inability to react limerently to more than one person at a time (e.g. being turned off to boyfriend or girlfriend while having a crush on somebody else)
5. Fleeting relief through vivid imagination (e.g. feeling momentarily better by imagining a wild scenario in which the LO becomes available)
6. Feelings of shyness and fear of rejection when around the LO
7. Intensification of limerent feelings by adversity ("impossible" love)
8. An "extraordinary ability" to interpret neutral behaviors as signs of hidden passion in the LO
9. An aching of the "heart" (central region of the chest) when uncertainty is strong
10. Buoyancy (a feeling of walking on air) when hopes are high
11. A general intensity of feeling for the LO which leaves other concerns in the background
12. A tendency to emphasize the positive and downplay the negative characteristics of the LO (Adapted from Tennov, 1979, pp. 23-24)
