How do i handle this......????

I have this best friend who's like the best best friend i ever had. Hes an amazing person, but sometimes i feel as though if it doesn't concern him nor soccer he just brushes it to the side. Like everytime i try to say something hes just like "oh ok" or "cool" then goes back to talking about something else. Then when i tell him about how i feel about this hes just like takes a breathe and says something that he thinks will make me feel better then i pretend to feel better and he acts like nothing ever happened. It just bothers me so much because its like i've thought about just cutting him out my life but its like i can't you know.
