Boyfriend doesn't put me first, What do I do or say to him?

what do you do when your boyfriend who claims you are all of his happiness is constantly putting you 2nd, 3rd, and 4th. His friends constantly come before me. I don't mind his guy time, becuase I need my girl time. I just get really tired of hearing "hey, I want to hangout but I'm just so busy.". it's funny, he is not too busy when he wants to do "certian things". HOnestly, I don't know what to do anynore., I ask very little of him...
