Am I living with an unevolved taurus man?

He is stubborn to the point that everytime I give him feedback, he brings up my mistakes. And when things don't go his way, he starts cursing at me. Insulting my character, trying to make me insecure etc.

He is incredibly emotionally closed off. Does communication even exist in his dictionairy? Feelings are inconvenient, and vulnerability feels threatening somehow. He starts blowing up when I try to have a deeper conversation. Basically he starts yelling, cursing when he feels challenged. He expects that people are loyal to him without doing anything.

For example, I had said something that made him laugh, however, he was suffering from a cold and it made him cough a lot. Then he called me a whore randomly because in his eyes, I had made him laugh on purpose, so that he would cough. I was so flabbergasted when I heard that. What an immature response. How was I responsible for that?

The person I'm talking about is my own twinbrother. I'm grieving the brother I could have had, but instead I'm stuck with this behaviour. We're both in our mid 20s.
