The Balcony Scene:
During the iconic balcony scene in Act 2, Scene 2, Romeo stands beneath Juliet's window and professes his love for her. As they speak, Romeo suggests that they could unite their families through marriage:
*ROMEO:* "Shall I hear more, or shall I speak at this?"
*JULIET:* " 'Tis but thy name that is my enemy. Thou art thyself, though, not a Montague. What's Montague? It is nor hand, nor foot,
Nor arm, nor face, nor any other part
Belonging to a man. O! be some other name
Belonging to a man."
*ROMEO:* " I take thee at thy word:
Call me but love, and I'll be new baptized;
Henceforth I never will be Romeo."
Here, Romeo suggests that if Juliet drops the name "Montague," which symbolizes their feuding families, he is willing to give up his family name and marry her.
Friar Laurence's Cell:
In Act 2, Scene 3, Romeo and Juliet visit Friar Laurence's cell to arrange their secret marriage. Romeo, overwhelmed with joy and anticipation, eagerly prompts the Friar to perform the ceremony:
*ROMEO:* "Come, come, with me, and we will make short work;
For, by your leaves, you shall not stay alone
Till holy church incorporate two in one."
In this scene, Romeo's urgency to unite with Juliet hints at his desire to solidify their bond through marriage.
The Wedding Night:
In Act 3, Scene 5, on their wedding night, Romeo and Juliet confess their love and longing for each other's presence even though they know about their families' feud and the threat of the law. When they eventually get alone, Romeo suggests consummating their marriage before he has to leave due to his banishment for killing Tybalt, Juliet's cousin.
