When Lady Capulet asks Juliet if she 'shall happily make thee there a joyful bride' what does Juliet's reply suggest?

This is from Act III, Scene
5.

First, let me point out that this is not a question. 
Lady Capulet is telling Juliet that she and Paris are going to get married.  Her way of
putting it is that

The County Paris, at Saint Peter's Church,

Shall happily make thee there a joyful
bride.

So she is not asking
anything -- she's telling.

So then look at what Juliet
says.  Basically, she says "no way."  She does not just tell her mom that she won't
marry Paris, she swears that she won't do it.  She
says

Now, by Saint Peter's
Church and Peter too,
He shall not make me there a joyful
bride.

So what does this
suggest?  It suggests that the relationship between Juliet and her mom (that was so nice
back in Act I, Scene 3) is no longer good.  Lady Capulet is telling Juliet what she is
going to do and Juliet is fighting back.  She is flat out refusing to do what she is
told.
