I'm stuck

Hello everyone here.
So I'm in a relationship with a guy since 2years now. He is not expressive. I had many issues with him regarding the same. It always felt like incomplete to be in a relationship where my guy can never make me feel special by expressing his feelings for me. He neither says nor shows. But whenever i put this in front of him he always says he doesn't know how to express but he loves me just like i love him. Even though I'm in a relationship it always felt empty. He never even speak about our future at least. 2 weeks ago we were on call. When we were talking, he was saying his frnds are getting married and all. So i took the advantage of the topic and mentioned when are u going to get married. The very next second he answered saying i don't get married only. Its like, we never even spoke about future even though i tried many times.. When we r finally talking about marriage, his answer bugged me so much. I mean is this what i expect? I felt like why am i even here with him. Its been 2 weeks since i stopped talking to him properly. He's been casually asking mr what's wrong with me but never really took an initiative to know why am i behaving strange. What should i do?
