I agree that you have to do your thing. We all know the balance between friend's zone and not are down to you making it clear that you want more than that. How explicit you are is something I am struggling with at the moment as I do things I want, but then forget about the girl's comfort... not wise.

You say you are kinoing and she is not responding. To me that is positive! All girls who let me stroke their hair or allow me to leave my hand on her knee are comfortable with me doing so. Just keep pushing the envelope and see how she reacts. If it's neutral then great, don't necessarily look for positive reactions from her.
