I give you credit for approach girsl you don't know and asking them out. I can't do that, but I am getting closer tho. But the reason I am replying is that when you force your self to talk to girls, they may see it and don't want to hurt you by doing anything to make you think that they are interested. I have found that if you show confidence in your self and are somewhat clam I tend to do better around girls I do not know. But I am not you so I don't know what would work for you.
