The nurse seems worried in Romeo and Juliet when she learns of Juliet's secret relationship with Romeo because she knows the implications of their families' feuds. She also worries about Juliet's well-being and the consequences of their forbidden love.
The nurse seems to be supportive and excited about the marriage in Romeo and Juliet Act 2, Scene 5. She is happy to be helping Juliet and Romeo arrange their secret marriage and wishes them well.
The excerpt from Romeo and Juliet does not seem to be provided.
TERRIBLE
I think Juliet is more mature because she dosent fall in love easily just like as Romeo.
Yep, the Nurse is like a real mother to her and her closest adviser.
He's a man of wax. That's a good thing, apparently. However, it does seem that the nurse would say this about any suitor for Juliet who was more or less male. After saying that about Paris, she is extremely complimentary about Romeo in Act II Scene 5. Then when it seems convenient to do so, suddenly (in Act III Scene 5) she's complimenting Paris again: "O! He's a lovely gentleman; Romeo's a dishclout to him."
If you read the play or watch it being performed, the answer to this will seem obvious. Against all odds, Romeo and Juliet fall in love with each other. That fact leads to everything that happens in the play after Act 1.
Yes, Romeo's feelings for Juliet are more passionate and intense compared to his feelings for Rosaline. With Juliet, he experiences true love, while with Rosaline, it seems more like infatuation. Juliet inspires Romeo to be more mature and responsible, while Rosaline's rejection leads him to despair.
The letter that was supposed to be delivered to Romeo informed him of Juliet's fake death plan. However, due to unforeseen circumstances, the letter did not reach Romeo which led to tragic consequences.
She threatens to kill herself, so the Friar says that he can give her a knockout potion which will make her seem dead for a couple of days, and then she can come back to life (and get together with Romeo)
Romeo dies first. Juliet drinks a portion which makes her seem dead, but Romeo thinks she really is dead and commits suicide. When Juliet is awake again, she sees dead Romeo next to her and kills herself.
Juliet is expressing disbelief that heaven would be jealous of her love for Romeo. She is questioning why outside forces seem to be interfering with their happiness. This shows her frustration and confusion at the obstacles that are keeping her from being with Romeo.
