I confessed to a girl and she gave me a question mark. What does that mean?

If you say you look like a girl, then he will give you a question mark. What he actually means is that he just can't believe your confession, or he means whether you confessed the wrong person, or whether you sent the wrong message, so I will give you a question mark directly. Then you can actually tell from his question mark that he is not interested in you. If he says he likes you, or he says he has a crush on you, it's interesting to you. Then after you confess to him, he will be in high spirits, excited and happy.
