I texted a girl that she was my girlfriend. She didn't refuse, but she didn't reply. What happened?

If you send a text message to a girl saying that you are your girlfriend, but she doesn't refuse you and then just doesn't call you back, then I think her not calling you back is the best reply. Because he doesn't feel the need to reply to you, because if she says to reply to you, it may cause you to pester him. So he doesn't think it's necessary, so he ignores you, because if a girl really likes you, she will definitely tell you. Ecstatic, unlike this girl. I won't reply to you a word.
