The lines from this excerpt from Act II, Scene IV, of “Romeo and Juliet”, by William Shakespeare, that reveal that Mercutio thinks Romeo would be better off if he stopped thinking about love are:

“Why, is not this better now than groaning for love?

…to hide his bauble in a hole.

Mercutio is saying that when Romeo is joking with his friends he is his true self, and he is better off than when he is groaning for love because when he is in love he acts like an idiot.
