Juliet tells Romeo that he should send her word about when and where to come if his love is honorable and his purpose is what?

And his purpose is marriage.

Romeo tells Juliet that he wants to marry her, but they have to have the marriage in secret because of their families' feuds. So, in response, Juliet says that Romeo should tell her when and where they were going to have it if he really is in love with her and if he really does want to get married.
