YeaItsAFourDoor,
This situation sounds like stuff that happens all of the time broski!! Don't worry about stuff too much man. Don't turn into me

You have to spend more time with her in order to develop what trace feelings you may have for her. The more time you spend with her, the better and more able you wil be able to understand her and see what her personality is like. About your friends, just tell them that everything is chill and that maybe you are just a little bit interested in her. Just try not to make a huge deal of it. Relax!! If she does like you, make sure she likes the real you and not an image you put up for her to fall for you. Good luck!
