Octavius sincerely loved his sister,

Octavius sincerely loved his sister, and he was so far softened by her
entreaties that he consented to appoint an interview with Antony in
order to see if their difficulties could be settled. This interview was
accordingly held. The two generals came to a river, where, at the
opposite banks, each embarked in a boat, and, being rowed out toward
each other, they met in the middle of the stream. A conference ensued,
at which all the questions at issue were, for a time at least, very
happily arranged.

Antony, however, after a time, began to become tired of his wife, and to
sigh for Cleopatra once more. He left Octavia at Rome and proceeded to
the eastward, under pretense of attending to the affairs of that portion
of the empire; but, instead of doing this, he went to Alexandria, and
there renewed again his former intimacy with the Egyptian queen.

Octavius was very indignant at this. His former hostility to Antony,
which had been in a measure appeased by the kind influence of Octavia,
now broke forth anew, and was heightened by the feeling of resentment
naturally awakened by his sister's wrongs Public sentiment in Rome, too,
was setting very strongly against Antony. Lampoons were written, against
him to ridicule him and Cleopatra, and the most decided censures were
passed upon his conduct. Octavia was universally beloved, and the
sympathy which was every where felt for her increased and heightened
very much the popular indignation which was felt against the man who
could wrong so deeply such sweetness, and gentleness, and affectionate
fidelity as hers.
