I once sent a text message to scold my boyfriend because he went back on his word and he ignored me. Today is the seventh day. What do you mean he ignored me?

Of course, he doesn't want to be scolded for ignoring you. It is wrong for him to break his word, but you can't swear. Nobody wants to be scolded, so it's normal for him to ignore you. If you don't want to lose him, you can take the initiative to ask him to admit his mistake and don't call names for a trivial matter. If you think that he always breaks his word and is not a person you can rely on, you can break up with him.
