His friends rant

My boyfriend would see me every so often but sometimes when I'm with him, he'll get a call off his friends and ask if he'd mind me going home so he can go out. Once he didn't see me for about 2 weeks but seen his friends and when he did see me he got a call off his friends to go out and he left my house to see them as he 'promised' them, it's like he's in a relationship with his friends and makes me feel like he doesn't like spending time with me. It's getting annoying now.
