Need help with romeo and juliet?

Act 2, Scene 2, Line 127.

"The exchange of thy love's faithful vow for mine" (2.2.127).

Torn between the impluse to run from her fears and the desire to stay with Romeo, Juliet tries to say goodnight to him. She tells him she hopes that their love, now only a bud, will bloom the next time they meet, and she wishes him the happiness that he has given her: "Good night, good night! as sweet repose and rest / Come to thy heart as that within my breast!" (2.2.123-124). It looks as if she's about to go, but Romeo exclaims, "O, wilt thou leave me so unsatisfied?" (2.2.125), and she asks, "What satisfaction canst thou have to-night?" (2.2.126). He answers, "The exchange of thy love's faithful vow for mine" (2.2.127). Romeo's answer seems to be deeply reassuring to Juliet, because after this she says hardly another word about her fears, and she starts making wedding plans. Perhaps the explanation for her change in attitude is that she thought Romeo was "unsatisfied" because he wanted sex, which would have confirmed her lingering fear that he might be the wrong kind of lover.
