Chasing girls, texting and pretending to ask questions, what is the most appropriate?

Depends on the girl's personality. Cheerful people don't like boys and mothers-in-law at all. It's no use pretending to ask questions. You can find something interesting to ask her out, such as the latest wonderful movies and delicious snacks. If you are afraid of embarrassment, you can first buy off the girls who have a relationship with her and go out to play together, which is justified and easy to close the distance.
