I feel like I give more than I recieve back, HELP!!?

Hi, I've been seeing this guy for about 7-8 months now and it feel I give more than I receive back. As far things like time, caring, priority and things like that. And I'm feeling like I'm not giving everything but I am giving a whole lot including these things that I listed. He gets upset when my parents interfere or when he can't have me to himself and things like that, but when I want the same thing from him, he seems like he has reason or he just doesn't want to. Like I know I have a busy life right now, but regardless I still make time for him. He does but he does try, but quite as hard as me. As for my friends and family (especially my guy friends), I still have them in the picture but instead of let them interfere with him and I and our relationship, I have let them know where they belong (not in a mean way) but in a way so I can make room in my life for him. But him on these other hand, with his friends (which are mostly girls) he says "Well I known him/her for years and blah, blah, blah....". And I felt like true but some his friends are in relationships (husband/wife, boyfriend/girlfriend) and even though they've may have even been friend with him way before they met the current person they're with, I know they're not going to put more priority on him than they do who they're with. They're going to be like "Yeah we friends and all but this is my husband/wife, etc. and he/she comes first." and they'd be right. Even his sister prioritizes between him and her husband. And I feel like he should do the same with him and I. I don't expect to be the center of his life, but I do feel like somewhere him and I should even out be on equal terms. Am I right? My biggest problem is how to expression this to him?
