In and ldquoMy Last Duchess by Robert Browning why did the poet use run-on lines?

Robert Browning's "My Last Duchess" does not employ run-on lines to any significant extent. While enjambment, or the continuation of a sentence or phrase across multiple lines, does occur in the poem, it is not pervasive and does not disrupt the flow of the lines. Typically, each line in the poem ends with a pause or punctuation mark, creating distinct rhythmic units.
