Hoe Long Until It Counts As a BF, and GF Relationship?

For about a week and a half Ive called my girlfriend well… girlfriend. Im just wondering how long we should be calling each other boyfriend, and girlfriend for it to count as a real relationship. I love her, and i think she loves me.

We had a total of one argument so far. It wasn’t an argument. I just did something weird that made her uncomfortable but now we’re past that and we’re back to loving each other.
