I have a friend. I sent her a message of blessing, but she never replied. I asked her to step on the empty space for me, but she refused. Every time I contact her, she doesn't contact me. ...

According to your description, I have two conjectures: First, she is a passive person. If she is timid and hesitant, then she doesn't take the initiative to contact you, which doesn't mean she doesn't care about you. Maybe she's just used to it or testing you. Secondly, she is an active person. If she is bold and outgoing and has many friends, then she doesn't contact you or even refuses your approach, which may indicate that she doesn't accept you very well, or that you have something that makes her mind.
