So on Halloween I went out drinking with some friends and noticed a girl that was from my bio class. I noticed everytime I saw her she would be looking right at me, and then I began to realise her staring at me in my labs. She would turn her body in a awkward position so she could easily take glances of me in the lab. I started talking to her and asked her if she wanted to study. She said yes, and I asked for her number. She gave it to me, but whenever I text her she takes so long to respond, and sometimes doesn't respond. So is she interested in me and simply is super busy so she cannot respond always, or is she just not interested.
I should also say sometimes we make eye contact and I smile at her, but sometimes she just looks down or away from me!
