This girl I've been into at the university, I liked her but i didn't make a move till i noticed that we would catch each other's eyes quite frequently. She'd also show signs of shyness when we'd pass each other (she doesn't look like the shy type tho). So i took it as a sign of interest and took action (actually i stumbled upon her in a shop and just had to talk to her). I was very nervous and so was she,  i could tell by the way she was acting and talking. we had some small talk and exchanged names and she went off. she did look back with a giggly smile as she left with her friend. So i made the mistake of finding her Facebook ID and texting to her there. I haven't gotten any reply yet (2 weeks, i became desperate so i even reached out to her on insta, my bad.) but the odd thing is that the other day as i passed her she gave me this long and warm, smiling eye contact for the first time.

​

TL;DR: girl i approached and reached out to on facebook messenger wont reply but still gives me signs of interest. i don't know what to do about it.
