Unbalanced relationship

My boyfriend cares a lot about his job and himself. He doesn’t care a lot about me (it’s the opposite to the song). I’m just someone who’s there with him, together with him to all the things he’s doing, supporting and surrounding him. That’s how I feel. It’s not that I share him with other people – he doesn’t have friends – but with things like his hobbies, his work and I’m not the protagonist in his life; I just exist. On the contrary I’ve put him unusually high to my scale of appreciation and to the top of my priority list. I know that the balance is not equal but I can’t control it. Once I’ll gain control and the situation will change dramatically I’m afraid.
