Romeo, before falling for Juliet, was deeply enamored with Rosaline. This infatuation is made clear early on in Shakespeare's play Romeo and Juliet.
Romeo's love for Rosaline is described as a consuming passion but ultimately unrequited. He pines for her, expressing his love in sonnets and expressing his sadness at her lack of interest.
Rosaline, however, remains unmoved by Romeo's affections. She is described as cold and indifferent, a stark contrast to Juliet's passionate nature.
Romeo's love for Rosaline serves as a foil to his love for Juliet, highlighting the transformative power of true love and the difference between infatuation and genuine affection.
The character of Rosaline, while not a major figure in the play, plays a crucial role in developing Romeo's character and setting the stage for his whirlwind romance with Juliet.
