What if a girl would text me one late night and ask me mentioning my name Are you still awake?

Well, it depends on what you mean. If you mean you think she likes you then yes, she probably does have feelings for you, or she could just be lonely. Also she could be needing a brother like figure a guess?? If it makes you uncomfortable then just dont say anything back, you dont ever HAVE to respond to texts I know I don't haha.(: Good luck.
