No, Lou Andreas-Salomé never married. She had many lovers throughout her lifetime, including Friedrich Nietzsche, Rainer Maria Rilke, and Sigmund Freud, but she never married any of them. She was a free spirit who lived her life on her own terms, and she never felt the need to conform to society's expectations of marriage.
