In Romeo and Juliet is there another reason why Rosaline doesn't want to be with Romeo?
Throughout most of Act I of Shakespeare's Romeo and Juliet Romeo is depressed over his unrequited love for Rosaline. Though she never actually appears in the play she is an important factor in establishing Romeo as a passionate and emotional character. Apparently she has spurned his affection, sending him into the doldrums, so much so that his father describes how he comes home and draws the shades in his room to block out the light of day. In Scene 1 he explains to Benvolio he is "out of her favor where I am in love" and that no matter what he does she has "forsworn to love." At one point Romeo alludes to mythology when he explains Rosaline's coldness toward his affection:
Well in that hit you miss. She’ll not be hit
With Cupid’s arrow. She hath Dian’s wit,
And, in strong proof of chastity well armed,
From love’s weak childish bow she lives uncharmed.
She will not stay the siege of loving terms,
Nor bide th’ encounter of assailing eyes,
Nor ope her lap to saint-seducing gold.
O, she is rich in beauty, only poor
That, when she dies, with beauty dies her store.
