Hey @Andre9 thanks for making this thread, I think it's such a relatable struggle.
As you said, there is no straightforward answer but from what you've said you have a good way of dealing with arguments. I agree that cooling off is a good idea, sometimes you need to do that otherwise the fight goes around in circles.
I recently made up with a friend who I had an argument with almost a year ago! It was a hurtful fight so we both needed a long time before we could talk again. When we were ready we explained what was happening for us emotionally at the time and acknowledged what the experience would have been like for one another.
We actually have a great article on how to tell a friend they've hurt you which I thought would be good to share 🙂
