Basically in the beginning of the fall semester of my freshman year of college(6 months ago) I had finished class and it was raining very hard outside, so I was waiting at the door for it to stop. This HB7 walked up to me and initiated conversation and we talked for about 10 minutes. She pretty much told me her life story. She said multiple times that she didn't know anybody at the school, without me asking, which I took as an IOI, also the fact that she initiated conversation made me think she was interested. The thing is though, that when I said I had to go let me get your number, she said her phone was dead and to put my number in her phone. We all know what that means. She never contacted me, and I didn't really care. The thing is, I just walked past her and she was staring at me for a long time. I assume in that situation she would've tried to avoid me. Basically I want to know, why would a girl initiate convo, give off several IOIs, and not contact me, and then stare at me later?
