Don Pedro describes them as being in "a merry battle of wits". Both of them want to be safe, to avoid being vulnerable to being hurt by the other. They therefore verbally abuse each other and the idea of love. In fact, they are attracted to one another as Don Pedro sees, but they are frightened by that attraction and by the unsafe and vulnerable position of being the first to confess it. Don Pedro and the others break down that fear by telling each of them (apparently without knowing it) that the other has confessed to being attracted already.
Why are they so frightened of revealing their feelings? There is a hint that Beatrice, at least, has already been hurt in love and doesn't want to repeat it.

In Shakespeare's "Much Ado About Nothing," Benedick is tricked into believing that Beatrice loves him through a clever ruse orchestrated by his friends. They stage a conversation in which they discuss Beatrice's supposed feelings for him, speaking loudly enough for Benedick to overhear. They describe her deep affection and longing for him, which ultimately leads Benedick to reconsider his feelings and acknowledge his love for Beatrice. This humorous manipulation showcases the theme of love and the playful nature of courtship in the play.
In Act I, Scene i of "Much Ado About Nothing," the messenger informs Beatrice that Benedick has returned from the war. This news intrigues Beatrice, as she and Benedick share a history marked by witty banter and mutual disdain. The messenger's mention of Benedick sparks Beatrice's curiosity and sets the stage for their playful interactions throughout the play. This moment highlights the tension between their past relationship and the comedic potential of their ongoing conflict.
