Romeo and Juliet Act 3, Scene 2 Summary

Juliet is impatiently awaiting nightfall, when Romeo is supposed to sneak into her room. She's hasn't heard about the fray yet.
When the Nurse enters, her behavior makes it clear that something has gone wrong. First, Juliet thinks Romeo has been killed. Then she realizes that her husband has just murdered her cousin.
Juliet's first reaction is to reject Romeo. She starts cursing Romeo, and the Nurse joins in.
Juliet turns on the Nurse and tells her she can't criticize Romeo.
"Will you speak well of him that killed your cousin?" the Nurse says. "Shall I speak ill of him that is my husband?" Juliet asks in reply.
Juliet realizes that if Romeo hadn't killed Tybalt, then Tybalt would have killed Romeo. Forced to choose between the cousin she has loved all her life and her new husband, she chooses Romeo.
But then she remembers that the Nurse also said that Romeo has been banished from Verona. She could deal with the fact that her cousin was dead, but not the thought that she can't see Romeo anymore.
Seeing her despair, the Nurse promises to find Romeo so that Juliet can at least say good-bye to him.
