Am I an asshole?

So I've been with my boyfriend for a year now and at first it was all butterflies but I soon realised that I cannot share a problem with him because he claims he doesn't know how to comfort and if I ever tell him anything he doesn't show any effort in even trying to make me feel better he just changed the subject. I've talked about it like so many times but it just doesn't seem to change that's why I've stopped talking about my problems with him. And if I'm not feeling like myself, the conversation would be dead, it would be silent and so very uncomfortable. I've had this huge crush on him for 6 years before he became my boyfriend and i was the one who confessed but the relationship feels so dead now and everyday I think about breaking up with him because I don't even feel like talking to him because it feels as if I'm going unheard and bearing his and my own problems and stress alone.
