On a blind date with a girl, we had a good chat during the blind date. She also asked me what constellation I was. When I got home, I texted her to ask.

Not necessarily. Girls are shy. You want people to be more active after you first meet them. If it is a boy, everyone should take the initiative to communicate. Maybe you two haven't found a common language, so you are not very enthusiastic about chatting, or girls are introverted, so you may not talk much. Let's keep in touch slowly for the time being. How long have you just known each other? It's a little early to say anything good! Hope to adopt!
