Quick answer

In a genogram, limerence is drawn as a slate (grey-blue) line with two small circles and an arrowhead pointing from the limerent person to the person they are fixated on. It marks an intense, involuntary, one-sided romantic obsession, as described by Dorothy Tennov, which is different from mutual love or secure attachment.

What is limerence?

Limerence is a psychological state of intense romantic desire and obsessive focus on another person, termed the "limerent object" (LO). Unlike mature love, limerence is characterized by:
  • Intrusive, uncontrollable thoughts about the person
  • Intense emotional dependency on perceived reciprocation
  • Physical symptoms: heart racing, trembling, flushing
  • Idealization of the limerent object
  • Fear of rejection reaching paralyzing proportions
  • Temporary elation when reciprocation seems possible

Dorothy Tennov's research

Tennov's 1979 book "Love and Limerence" identified this as a distinct psychological state separate from love, attachment, or infatuation. She described limerence as commonly lasting from several months to a few years, though it can persist indefinitely without consummation or rejection.

Clinical significance in family systems

Limerence appears in genograms when documenting:
  • Affairs where one party is limerent rather than in love
  • Unrequited attachments affecting family dynamics
  • Historical relationships that still hold emotional power
  • Patterns of obsessive attachment across relationships

Limerence vs. love

Relationships may begin with limerence and evolve into love, or limerence may persist destructively.

Limerence in affairs

A common clinical presentation involves a married person experiencing limerence for someone outside the marriage. The limerent person may:
  • Believe they've found their "true" soulmate
  • Compare their spouse unfavorably to the limerent object
  • Make impulsive decisions based on limerent feelings
  • Experience withdrawal symptoms when the affair ends

On the genogram, the limerence line can sit alongside an affair line between the same two people. See how to show an affair.

Frequently asked questions

What does the limerence symbol look like on a genogram?

It is a slate (grey-blue) line with two small circles in the middle and an open arrowhead at one end. The arrow points from the limerent person to the person they are fixated on (the "limerent object"), because limerence is one-sided.

What is the difference between limerence and love on a genogram?

Limerence is obsessive, anxiety-driven and focused on gaining reciprocation; love is mutual care, security and focus on the other's wellbeing. GenogramAI draws love and in love as green lines with circles and no arrow, while limerence is a slate line with an arrow pointing one way.

When should I use the limerence symbol?

Use it for affairs where one party is limerent rather than in love, unrequited attachments affecting family dynamics, historical relationships that still hold emotional power, and patterns of obsessive attachment across relationships.
