In 1879, while in Naples, she met journalist Martino Cafiero, and became involved in a fast-paced love affair with him. However, less than a year later, while she was in mid-pregnancy, he left her. The baby did not survive birth, and shortly thereafter Cafiero died as well. Duse then joined Cesare Rossi's theater company, and met actor Tebaldo Checchi (pseudonym of Tebaldo Marchetti). The two married in 1881. By 1882, the couple had one daughter, Enrichetta Angelica, but divorced after Duse became involved with another actor, Flavio Andò.
