When he says "My will to her consent is but a part; An she agree, within her scope of choice Lies my consent and fair according voice." He is saying here that his consent to Juliet and Paris' marriage is "but a part" of the decision, so he believes that her choice is also needed. He says that, while his "consent and fair according voice" may play a part in her choice, she still has a choice, free will.

-Personification is shown in this excerpt, specifically in the line "I saw the dull yellow eye of the creature open; it breathed hard, and a convulsive motion agitated its limbs." Because the author is giving human like characteristics to the light.
2. Mingled with this horror, I felt the bitterness of disappointment; dreams that had been my food and pleasant rest for so long a space were now become a hell to me; and the change was so rapid, the overthrow so complete!
- The line "for so long a space were now become a hell to me; and the change was so rapid, the overthrow so complete" uses a metaphor because the vents that take place aren't literally hell, but they are describing it in a way that makes it feels that way.
Basically she is saying "i love you so much i would do anything for you and i will miss you until i see you again tomorrow."
