"Is Rosaline, that thou didst love so dear, so soon forsaken?" (2.3.70-71)
"Thou chid'st me oft for loving Rosaline... And bad'st me bury love." (2.3.86-88)
Romeo and Friar LawrenceFriar Lawrence's cell
"Not in a grave. To lay one in, another out to have." (2.3.89-90)
"Her I love now Doth grace for grace and love for love allow. The other did not so." (2.3.91-93)
Romeo is telling Friar Lawrence that he is now in love with Juliet, and he is trying to convince Friar to marry them.
"But come, young waverer, come, go with me. In one respect i'll thy assistant be, For this alliance may so happy prove To turn your households' rancor to pure love." (2.3.96-99)
The idea that true love is unexpected is shown here, because Friar Lawrence is deceived by Romeo, because he believed that Romeo wanted to marry Rosaline. At first, Friar Lawrence does not believe that Romeo could possibly be in love with Juliet, because he has moved on too quickly from his previous love. This shows that love can be deceiving.
