I'm really sorry about this...

당신 don't need to feel bad about coming here and asking for advice; this is what this spot is for. If someone is sick of it, then they obviously don't belong in a place like this. People are going to ask questions, and they always have that right; ask away.

당신 need to tell your friend not to correct 당신 all the time, first off. If 당신 get something wrong -- the name of a place, a grammatical error, whatever it is that people get wrong often -- then it's fine for someone to remind and correct. Then 당신 forget about it later, simple as that. But if she rubs it in all the time, such as like 당신 said even when you're right about something, just tell her that 당신 don't need any 더 많이 input. 당신 obviously don't like it, but 당신 need to tell her without getting into a fight. It's all about word choice -- use I-statements, NEVER you-statements.

At least 당신 two are saying sorry, though. It's better off than to get into a fight and be mortal enemies for the rest of your lives, only to realize at the last moments that what you've both been doing was wrong. I really think that, after your discussion with her, 당신 both should keep a bit of distance for a 일 또는 two. Let the words from the discussion kick in; think about it for a while. It's better off to think of what 당신 two have fought about and realize that it's just not worth it.

If things keep going the same way, then 당신 either keep working at it 또는 just go off on your different ways. I'd rather 당신 not do the latter, but if 당신 can't seem to make things any different, then I don't know what else to say here. Not everyone is right, and both of 당신 have to keep that in mind. No one should be that conceited and full-headed to think that they know every single thing in the world; it's just not possible. It's not a very good thing for someone to have in a friendship; it's a barrier. That also goes for fighting over things that don't even matter. If it happens again, take some distance like before.
