Why did he scold me as soon as I sent him a message? I didn't do anything else. Is it because he hates me?

First of all, is there any misunderstanding between you? Generally, normal people send messages to each other, and the other party will not respond with rude names. Secondly, whether the information you sent him stimulated his bad comments, otherwise, he didn't need to scold you. Another possibility is that if you are a man-woman relationship, it is possible that he can't tell you anything and wants you to leave him in this way.
