Need practical and genuine advice from men

So I was with this guy for more than a year almost 1.5 yrs. In between we broke up several times and it was sometimes from my side from his. We had almost everything in common so many things but or ways of seeing things was different. He has anger issues. I understand that. He has apologised about that several times. We both tried to make it work. It’s that we are in the same College and ofc we have to see each other everyday. For me small gestures matter he never paid attention to them. Yesterday it was something extremely big. We had to fill our forms related our studies. But night before that we had a fight because of something he had done. I still called him in the morning to wake him up but later I found out that he was already there. I asked him to atleast have informed me while I was calling him to be there. He said “why would I care about you?” I said nothing and left. I have blocked him. How do you make a man realise that he was at fault atleast?
