Arguing with boys, he deliberately didn't read the text messages.

He ignores your phone calls and text messages, which means he is angry (hates you) or angry (wants you to please him). He asked you to think about it, and then ignored you for so many days. There are two possibilities. The first is that he may be a rational person and will not change his attitude until you figure it out and admit your mistake. The second possibility is that he is stingy, but as long as you spend some time trying to please him, it will be OK.

As for the message you want to send him, I don't know what you are arguing about or what your feelings are, but boys generally have strong self-esteem and love face, especially in the face of people he likes or loves, so yelling at him may not only make him angry, but even hurt his self-esteem. Do you know how to do it?
