When did you meet your boyfriends friends?

Gracie

My boyfriend and I have been dating for 8 months and I still haven't met any of his female friends. I've met most of his male friends, but not a single female. I know he has female friends because he texts snapchats them in front of me. Yes, he's sent them pictures of us together, they know we're a thing. I've met a large potion of both sides of his family having been invited to weddings and other big events, but I still haven't met a female in his life that's not his family. I got to thinking last night and this is really bothering me. It's not for lack of trying on my part, I'll ask when I get to meet someone and he'll always say "oh [girls name] is out of town." We're in college so i get that his oldest female friends go to different schools, but we both stayed in town for the summer (he grew up in the same city as the school) and conveniently all of his female friends were ONLY back while he was gone on family vacation. Is this weird? Am I over thinking it? At almost 3/4 of a year dating I feel like I should have met one at least in passing. At what point did you meet your boyfriends female friends? Why would he not want to introduce us?
