Okay, boyfriend trouble.

I just got home from hanging out with my boyfriend. I left because his friends got there.
Lately, we've been having some issues. He is paying more attention to his friends than he is to me, and I dont want to seem like I'm a bad girlfriend or something, but is it normal that he doesn't text me back when he goes and hangs out at his friends houses? Or doesn't take the five seconds to just tell me that he's going somewhere so that when i try to call him, and get the ignore button hit on me? Not to mention the fact that he is ALWAYS with some other girls when he goes over there. Is this like...right? I mean I know that he would flip out if I ever pulled this kind of stuff. But he does it almost everyday. The people that he hangs out with are bad, and I dont trust them. I just worry that something is going on behind my back. (I'm a veryyyy paranoid person, but come on, dont I have a reason to be??) I need answers, someone helpppppp meeeee!!!!
