need help

I don't know what to do when my boyfriend and I started dating we were great but now like a month or two later it's just like nothing he doesn't want to be around my friends or family and he promised me he was gonna make an effort to be around them but all he wants to do is sit around at his place drinking beer and smoking weed and Ive already hung around his friend and smoked with them even though his friend gets on my nerves but I don't say anything out of respect for my boyfriend but he promised he was change cuz he can be an ass hole but his friend doesn't help and we don't even talk that much anymore
