Depends. Are you looking to be friends with her? If so, continue on and act friendly towards her. If you are looking to date and hopefully have sex with her, you need her to see you in a different light. Just remember, the ladies want to have sex with the rough and azzhole type, not the friendly type. You want to create sexual tension, not a friend atmosphere. It seems that is what you are creating now; a friendly atmosphere. If you are not a challenge to her and different than other men who orbit her, she'll just keep you in the friendzone. Need to invite her out to drinks or the park and talk about things that would strike an emotional response. Ladies work off of emotion, not logic (in terms of feelings). Even an angry emotion means she's feeling something towards you. Notice how anger, aggression (non-violent) and sex are correlated in the movies?
