Girls don't return my messages for several reasons.

There are many kinds of situations, good and bad. You've only known her for a few days, but you don't know anything about her. If you know her life arrangement and her temper, you can make a better guess. I know you have this mentality of being swayed by considerations of gain and loss. When you get in touch with her and have a good impression on her, you just want to spend more time with her, and she doesn't have that enthusiasm now. Don't take this problem too seriously. If you must know, when you meet her face to face today, pretend to be casual and ask her, "Did you hear from me last night?" Look at her answer and performance. Maybe he just fell asleep.
