Let me first say thank you for your time and I am eager to see what you guys think.
This girl has the same class with me once a week and for 6 weeks I never spoke to her at all! I always noticed her looking at me but didn't know what to think. I beat her in an exam (me and her both got highest marks and I beat her by a point) I then, being a bit crazy said "Haha I beat you now and I will beat you again!!!". She laughed and said "Damn" jokingly.
The next I saw her walking to class and I made it look like I was texting on my phone, she opened the door, turned around to me, arched her neck and said "Hey", I said hey back and made a comment about her being the teacher's pet. Near to the end of the class I put my phone on her desk, she looked at me, I did a motion with my head and she put her number in my phone.
We texted for a week, it was playful, teasing etc. Got a lot of

from her. Then when the class came around again, I asked if she wanted to have chinese food, but some guy tagged along. I didn't mind at first and I was taking the piss outta him any way I could and she laughed every time. I suggested coffee first, I got her to hold my hand, teased her and made some funny remarks about women etc. She was asking my opinion alot on the subject we learn together and if I can explain certain theories to the other guy, which I did.
We went to the restaurant, all three of us, the dude left early, and I was maintaining eye contact, played the 5 lies game and got a kiss on the cheek from her. She mentioned how romantic the scenery was. I noticed when I was looking into her eyes her pupils dilated massively. When we were ready to leave she commented on how time had flown by without her realising and started to giggle, I askd her why and she said "I was looking at your face when you were putting your gloves on and you were concentrating so much".
Anyway, when I got home she texted me referring to a conversation we had earlier and how she "just had to share it with me" when she realised something.
Now, two days later I see her around college and shes smoking, looking VERY stresses out. She told me she had a lot on her mind. Before I saw her though, she didnt reply to one of my texts. Shes gone abroad now to see family and I wont see her for a month... What should I do? Can I reignite the fire again after so long?!?!?
Thanks guys!
