My girlfriend suddenly ignored me today. I met him online, but she stopped talking. I know he is busy, but he won't ignore me. He's right.
Maybe you are used to her looking for you and chatting with you every day, but today she suddenly ignores you and you feel unaccustomed. First of all, you can't worry, or she will talk to her later. Maybe she was busy when you looked for her. If she doesn't talk to you again, you can wait until everyone is free to make it clear. Maybe you care too much about her.
