You said that a girl sent you a text message late at night saying that she was scared, so what is your position in that girl's heart?

I think she has a vague feeling between friendship and love for you. Maybe it's because you've been together for a long time and she has a crush on you. Even if she is scared in the middle of the night, she can send you a text message to show that you occupy the first place in her heart. You can try asking her! If you have a good impression on her, you can boldly tell her, which is very possible! I hope it helps you.
