"O Romeo, Romeo, wherefore art thou Romeo?"(2.2.36)
Romeo and JulietJuliet's Balcony
"Deny thy father and refuse thy name," (2.2.37)
"Or, if thou wilt not, be but sworn my love," (2.2.38)
Juliet is discussing the what will happen if they end up together. (Deception)
"And I'll no longer be a Capulet." (2.2.39)
Romeo's confession created many more issues for Juliet. Although she feels the same way, it will be almost impossible for them to be together because their families are enemies. Juliet feels helpless because she wants to be with Romeo, but at the same time she can't ruin her family's reputation.
The idea of love is definitely playing a huge role in Juliet's decision making because she's not thinking straight. She's willing to give up her entire family for an enemy's love. She's letting the idea of love blur her vision of reality because she believes her and Romeo will live a perfect fantasy.
This relates to the motif of deception because Juliet is letting the idea of love deceive her into believing that Romeo's love is more important than her entire family and her future as a Capulet. Shakespeare is demonstrating through Juliet's decision making that love can blur one's vision of reality.
