Boyfriend probs

Okay so me and my boyfriend of 9 months have had an amazing relationship and we seem to be really good together but lately I've been realizing just how much more I care and focus about him and he doesn't me. I'm not saying he doesn't care about me but I just feel like I'm the one carrying the relationship. I know I shouldn't feel like I need to work for his attention but that is how I'm feeling. What do I do? I've already told him how I felt multiple times and he has fixed some things but I'm still feeling like something's no longer right between us. I'm not tryna breakup with him whatsoever but I just need advice
