So last night i was at a night club with people from my university. This girl who has been smiling at me/looking at me for months was there (i was picking up choosing signals) and she was doing so that night as well. I am in an LTR so i thought fuck it and called her out on it when we were alone. I told her i had noticed and was curious about her intentions. She acted like it was nothing, like "i guess im just smiling at everyone" etc. What happened? Any advice for further encounters with this girl?
