The girl takes the initiative to send me messages every day to share her things with me, and her tone of voice is always coquettish to me?

These behaviors of this girl show that he likes you, so he will take the initiative to send you messages to share his things with you, and act coquettishly with you in front of you. And also get jealous.

It’s good that I like you, but it may be because of his personality or that he doesn’t like to say dirty things. If you like him, don't do anything he doesn't like. After all, everyone has their own preferences. Some people like it, but that doesn't mean everyone likes it.

To love someone is not to love him in a way that you think is good for him, but to love him in a way that he likes. Only in this way can the relationship between two people become deeper and deeper.
