Hi Samantha,
I wouldn’t worry about it. His friends and family have already pegged you as his girlfriend. You’ve been going out consistently with only each other for a while now. In fact, I wouldn’t be surprised if people are all like, “How’s yr. GF?” and he responds, “She’s OK.” It would be very adolescent for him to be all, “She’s not my GF! We’re just friends! Why would you think that?!”
When you bring it up as a question and not as a fact, you’re just making it worse.
Have someone ELSE introduce the two of you to a third party. i.e. “Pierre, this is Samantha and her BF Keith.”
If he doesn’t deny (he won’t) then BOOM! Cannon!!
Good Luck,
Inky
