Breakup or not

I'm in a relationship and I communicate very well & also I like to express my feelings. Every disagreement or argument we had I've been the bigger person and fixed it even when it wasn't my fault. He never think he's  capable of any wrongdoing & he sometimes think I'm trying to start an argument by me simply just communicating my feelings. I'm just tired of always being the bigger person and fixing this relationship when he makes no effort.
