What should I say when texting a girl I just met?

You did the right thing. The first step to get along with a girl is to analyze her personality. You think she is shy. If your analysis is correct, I suggest you send a message implicitly. First of all, you should send her two words "good night" before going to bed every night. It doesn't matter whether she received it at that time. As long as she wakes up the next day, she will be very moved. You should make her feel that you care about her all the time. You should say it directly, not with sweet words. This type of girl doesn't like glib boys. You can say, are you free tomorrow, can we go ... Forget it if you don't have time Really.

I wish you success.
