Girls, when guy calls you in the middle of the night to see if you are ok?

Anonymous
I like this girl a lot and we've been quite hot and cold lately.
We also have a small group over Facebook and she posted there that she is supposed to go somewhere and she is a bit scared.
So i message her at some point, asking if she is ok and if she got home, knowing that she usually answers these pretty fast. She did not answer for some time, so i called her. She did not answer that either.
She eventually answered over the messenger app.
She said "thank you for caring :D" and when i jokingly told her i am traumatized by her not answering she said "awww, huuug"
Two questions:
1. Do you get it as interest if the guy calls in the middle of the night to see if you are ok?
2. The fact that she thanked me for caring and all, would that mean anything?
