Three words, dear Romeo, and good night indeed.
If that thy bent of love be honourable,
Thy purpose marriage, send me word to-morrow,
By one that I'll procure to come to thee,
Where and what time thou wilt perform the rite;
And all my fortunes at thy foot I'll lay
And follow thee my lord throughout the world.
I included these lines from Act II, scene ii as a set for you to analyze about Juliet's feelings for Romeo. I am not quite sure what you mean by analyze, so I will give you some ideas in terms of comprehension, literary device and real relationship.
First, these lines occur during the balcony scene as the lovers say their good night salutations. She is essentially saying, "Dude, if you are serious about all of this, I'm in. Send someone to meet me tomorrow after you secure our marriage plans and I will be there. Then, she says she is willing to give him everything she has: riches, love, her very being.
I find it interesting that she says "Three words" because we don't know what those are, but my mind goes right to I love you when she says that. She also figuratively makes him into a worshipful figure as she tells him that she'll lay everything at his feet. The effect of this is to demontrate the devotion she is willing to give him.
These last couple of lines are key because they show her willingness to sacrifice who she is for the chance to be in this relationship. That is generous giving. That is courageous charity. This will be a risky relationship.
