I was at lunch earlier today with the few friends I have, one of whom I have strong feels for and while we were walking to lunch she hugged me and locked her arm in mine. During that I smiled at her, she said that she had never seen me actually smile(I haven't truly smiled in a long time), then she asked why I was smiling, I replied by saying that it was her. During lunch and after she almost completely ignored me, which of course pissed me off a bit. I can't understand it at all.
