A girl, she refuses to tell me to her face, but she always sends me text messages saying I don't care about her ... What does that mean?

Well, the feelings between men and women are very subtle.

Maybe she likes you a little, and maybe she's struggling.

Let it be,

We can't get on the pole, nor can we be too cold to others.

In fact, girls are cheap leather. The more you care about her, the less people take you seriously. The less you care about her, the more she gets on the pole. I suggest you let nature take its course.
