Texting a girl "I love you", she replied "silly" and then it was gone. How does this girl feel about me? Please answer.

Maybe when you are joking, the most important thing is to see how you get along with that girl. If you usually have a good relationship with that girl and suddenly you confess to her, then she will think you are joking, and confession depends on the atmosphere and environment. It's better to pave the way for QQ or WeChat first, and then gently mention that you like a girl. It's easier to cut in. If you have nothing in common with that girl and you have a crush on her, then I suggest you talk to the girl you like better from tomorrow, otherwise you will suddenly confess to her and others will ignore you.
