I think this is referring to this bit of dialogue:
Romeo: Lady, by yonder blessed moon I swear...
Juliet: O, swear not by the moon [ ... ] lest thy love prove likewise variable.
In other words, she's not telling him not to swear his love, she's telling him "Don't swear on the moon. It changes. I don't want a love that waxes and wanes."
If you meant something else, please be more specific.
Juliet tells Romeo not to swear his love by the moon because the moon changes over the month and if Romeo swears by it his love will be variable.
Because the moon is inconstant and ever changing, and Juliet wants to know that Romeo will love her forever.
not to swear at all ....actually first she askes him to swear by himself...then not to swear at all It's the other way around. "Do not swear at all; Or if thou wilt, swear by thy gracious self, Which is the god of my idolatry, And I'll believe thee."
Juliet: "Romeo, Romeo, Wherefore art thou Romeo?"
hope from Juliet, romeo and the friar that romeo and Juliet will live together in love for the rest of their lives.
Early in the play, Romeo and Juliet meet at the Capulet's party and they both fall in love at first sight.
Juliet asked Romeo to swear his love for her and to pledge his loyalty.
Because the moon is inconstant and ever changing, and Juliet wants to know that Romeo will love her forever.

"By yonder blessed moon I swear--" But she doesn't like that very much.
Juliet, of course.
romeo and Juliet
Apart from Romeo and Juliet, nobody.
Juliet: "Romeo, Romeo, Wherefore art thou Romeo?"
hope from Juliet, romeo and the friar that romeo and Juliet will live together in love for the rest of their lives.
Early in the play, Romeo and Juliet meet at the Capulet's party and they both fall in love at first sight.
hmmm... seems kind of obvious to me.
A motto for Romeo and Juliet might be forbidden love.
