Why did octavian not trust Antony and Cleopatra to ruler?

Octavian did not trust Antony and Cleopatra due to their close alliance, which he viewed as a threat to his own power and the stability of Rome. Antony's decision to align himself with Cleopatra, a foreign queen, fueled suspicions that he was prioritizing her interests over Rome's. Additionally, Cleopatra's influence over Antony and their shared military ambitions raised concerns about their potential to undermine Octavian's authority. This distrust ultimately contributed to the conflict that led to the downfall of both Antony and Cleopatra.
