It's not SO bad!

Depending on what kind of fights/arguments you get into it can sometimes turn out to be a good thing. When arguing you would often find out more about your partner.
My b/f and I have small arguments now and then, but I find out more and more things about him and it brings us closer.
This might not accure to everyone but it does to a lot of people even when it comes to a friendship with someone.
Having an argument isn't always a bad thing. So don't stress about it unless it gets really bad.
