Chasing a girl, I want to send her text messages and talk to her every day, but I'm afraid she's bored. What should I do?

Chat with her at a fixed time and get her used to receiving your call at a certain time. Chatting mainly talks about her heart, without making comments, just listening and occasionally inserting a few words of her own thoughts. Then after a while, don't call her occasionally. If you don't call her occasionally, but she calls on her own initiative, it proves that she is at least used to you and has a certain affection for you.
