I like a girl. Every time I send a text message to her first, she replies in time (except that she has something to do). What does she think of me and her?

When she was in college, she should have hesitated about you, but she still had concerns. Maybe, as you said, distance made her flinch. Personally, she feels like your good friend now. Although sometimes it is still a bit ambiguous, a lonely girl still wants someone to care about and love her. I don't know how good I am at taking her away. And now you are confident, can you give her happiness? If there is, go to her, don't let yourself give up without trying, as you will regret it in the long years to come.
