In Act 4, scene 3, of Shakespeare's Julius Caesar, how do Brutus and Cassius resolve their dispute?

In Shakespeare's Julius Caesar, it
seems that Brutus and Cassius resolve their dispute in Act Four, scene three, by
talking. These men have been together as friends for a long time. Their conversation
becomes particularly heated, and they throw insults at each other. Brutus is angry, for
one thing, that Cassius would not give him money to pay his army. Brutus accuses Cassius
of acting unkindly to Brutus where he would never have done so with
Caesar.

Cassius wonders that a friend (Brutus) could find
fault with his friend (Cassius). However, Brutus is critical of the
way Cassius acts—of his faults. Cassius thinks that a friend would overlook another
friend's faults, but Brutus says he will not sink to
"flattery."

When Cassius calls on Ocatvius and Antony to
kill him as Cassius and the others killed Caesar, Brutus relents. He buries his anger,
pledging his friendship once again to Cassius. Then Brutus explains that with everything
else that has happened since the assassination, that he has also received word that his
wife Portia has killed herself. Brutus is devastated.

The
two men agree that they will not allow anger to come between them
again.
