title should say with a bunch of HER female friends

I hate being in large groups of people, especially when the majority of them are females.

Should I just ignore them, unless they introduce themselves first, or ask me a question?

I'm usually just quiet in these situations and only talk to the girl I'm seeing. I don't care what her friends think of me, but if they do try to talk to me I will be nice and talk back.

I'm 19 if that matters.
