Answer:
Are these Romeo's lines you are referring to?
Which thou wilt propagate to have it press'd
With more of thine: this love that thou hast shown
Doth add more grief to too much of mine own.
If so, I believe the correct answer is the first one - Your love and concern are making me feel even worse.
Step-by-step explanation:
He says in the excerpt that her love adds more grief to that which he already has a lot of, which makes the first sentence the only possible option here.
