Romeo and Juliet 1.1 Wordplay: "a word ill-urged"

The transcript discusses the word 'sadness' in Shakespeare's time, which meant both unhappiness and seriousness. It highlights how Romeo finds the use of 'sadness' inappropriate when urged to act seriously, as he is already unhappy due to unrequited love. Eventually, Romeo responds to Benvolio, using 'sadness' in both its meanings, acknowledging his love for a woman.

In what way does Romeo eventually respond to Benvolio's urging regarding his feelings?

What does Romeo mean when he says 'In sadness, cousin, I do love a woman'?
