Ask your girlfriends about their brothers and their brother's friends!
Don't worry about that, the important thing does your girlfriend like you.
You are being possessive and need to give him space. If you don't do this he won't be a boyfriend for long. Do you have girlfriends? Do you like to do things with them? If he told you what to do with your girlfriends how would you feel? You wouldn't like it. The same with him.
He's using her for sex. Tell them to break up.

Well think of it this way: Who is more important to you? Your best friend or your boyfriend's friends?
Well besides the gender thing, some girls also refer to their close group of friends who are girls as their ''girlfriends'', and some people boys as ''boyfriends'' but pretty much other than that nothing besides that boyfriend is referring to males, and girlfriends to females as i mentioned.
The most important people are your family, boy/girlfriends, and friends.
