Fights in a relationship

Everytime we fight, I want to be closer and resolve it, he doesn’t answer calls or texts. When I call repeatedly it becomes my fault and I tend to become anxious because of past experiences too. Even today’s I told that , “Let’s speak properly for a minute and I’ll let this go” and he said that “ I won’t” Finally he says,” Everyone has a life because you get anxious can they not sleep “ Who’s wrong here ? I’m asking genuinely.
