Bros over me?

I need some help ladies. When you are in a relationship, Should you be your boyfriends first priority or his 'bros'. Lately i have felt like a burden not a priority. Tonight a guy texted him asking if my boyfriend could pick him up while we were hanging out and my boyfriend said no. He turned to me and said that he needs to come up with a reason why he cant and i said just say your on a date with your girlfriend. And he said no because that will look like i picked you over my bros and that breaks the Bro code. I really dont know how to feel. Do i talk to him about it or what?
