I'm an M20 from Denmark that met a F19 in one of my university classes. Started off slow but we always exchanged glances, smiles and greetings until one day she approached ME and we hit it off, walked a bit together and started sitting next to each other in class.

A few days of this (I even experimented and changed my seating location to see if she would to and it worked lol) and I eventually went and had breakfast and coffee with her and we chilled together pretty much the entire day. The body language she was giving me so so obvious! She kept sitting closer to me on the couch, looking towards me and smiling whenever someone said something funny, making sure I liked her friends, and she even rested her head on my shoulder for a brief second when I said something funny. I gave her my number later and left because I had an exam and literally when I finished I saw that she texting asking me how I did. We chatted for a bit.

Then the next day I saw her and she approached me and my friends and she talked to me. She started saying how she thought of me all the time as she studied for her exam yesterday. She was busy studying with her friends for their exam so I didn't see her much that day. Then after she finished I saw her, we talked for a bit about how she did and stuff and that was pretty much it.

Ever since then she has been a bit dry for some reason. She still sits next to me in class (obviously following which seat I pick, even if it meant not sitting next to her best friend) but she doesn't initiate conversation and out of class I haven't been sitting with her, nor has she texted me.

Not sure what's going on here. Any advice?
