Does he think I'm his girlfriend?

we been dating for 2 months and yes.. sleeping too since I'm in my mid 20s and he's in his 30s.

we text everyday and sometimes call and meet about once or twice a week and yesterday we had a small..really small

argument? well not really an argument either..we just didn't understand each other so kept asking what the other one meant..

and he said

"wow we are having our first fight!"

i didn't say anything then but I thought 2 people had to be in a relationship to even call having a first fight..

so..ladies and gentlemen.. am I over analyzing or do you think he actually thinks I'm his gf?
