How will you know if a girl isn't feeling aloof around you anymore? PLEEASE! There's a group hang-out tomorrow?

I confessed to my close friend before that I like her and she told me that we'll still be friends. But many days later I told her that I didn't like her anymore even though I still did.. I just didn't want her to feel aloof and concious around me. So how do I know? 10 points~!!
