@nkaykae212,
You should always have closure in my opinion if that is what you want.
By that I mean, you two never spoke after the argument and you should have so that you could both understand what occurred and why.
What was the argument about? If you don't mind me asking.
Maybe if you both had the chance to discuss "that" you both may laugh about it now (or work towards that) so that eases the tension and allows you both to openly decide and discuss what it is that you mean to each other and then proceed from there.
People aren't mind readers.
