With the single exception of Falstaff, all Shakespeare's characters are what we call marrying men. Mercutio, as he was own cousin to Benedick and Biron, would have come to the same end in the long run. Even Iago had a wife, and, what is far stranger, he was jealous. People like Jacques and the Fool in LEAR, although we can hardly imagine they would ever marry, kept single out of a cynical humour or for a broken heart, and not, as we do nowadays, from a spirit of incredulity and preference for the single state.
