OK, awesome girl shows a lot of interest, me being clueless doesn't understand, when I finally get it she already feels like I rejected her. I asked her out she said she would think about it. I backed off taking this as a no. I still chat with her but was conscious to dial it down. If I did get a little flirty she shuts down. The last two weeks she has been more engaging, giving me compliments, sitting next to me, etc. I can't easily suggest hanging out due a number of reasons, one is fear of scaring her off again, another is different social groups. Do I just match her flirting and let her escalate it?
