How does Romeo arrange the marriage?
In Act II, Scene 3, which immediately follows the famous balcony scene where Romeo and Juliet pledge their love for each other, Romeo goes to see Friar Lawrence with the express purpose of declaring his love for the "fair daughter of rich Capulet" and asking the friar to perform the marriage between he and Juliet. He hopes that he can convince the friar that he is truly in love with Juliet even though the day before he had been madly in love with another girl named Rosaline. Friar Lawrence quickly rebukes Romeo, condemning his idea of love:
Holy Saint Francis, what a change is here!
Is Rosaline, that thou didst love so dear,
So soon forsaken? Young men’s love then lies
Not truly in their hearts, but in their eyes.
Bid her devise
Some means to come to shrift this afternoon,
And there she shall at Friar Lawrence’ cell
Be shrived and married.
