I'm feeling I need an apology after an argument that I had.
I understand that, have you reached out to talk to this friend?
There's no need to talk to a friend , I definitely want an apology
Disagreeing with others is inevitable. You probably need to apologize just as much as the other person.
I just want my apology. He's the one that caused the argument, he should apologize first, it's only fair.
I understand what you're saying, but you may be at a standstill for a long time. Instead of waiting, you should communicate with your friend that you think he owes a apology. That way you can both get over the argument that you had quickly.
