What's it like to send a text message to a girl who once confessed, but answer the phone on the phone?

First of all, there are two possibilities for not returning messages. First of all, she received too much news to read. The second is that she doesn't want to reply to your message and give you an illusion. Answer the phone because it will embarrass both sides if she doesn't answer it. She is completely polite, so get out of here before you get too deep.
