I kinda know this girl from like 2 years ago. I was in ONE day of her art class, but she was so damn cute. Then I learned she was already dating somebody and I kinda forgot about her until I saw her profile on facebook through a friends account. Shes done like her first year of Uni now going into her second and I dont know if shes still with her boyfriend (highly doubt it). Basically I want to know how to talk to her. She dosnt know who the hell I am or how I know her. I dont go to the same uni as her and I only know a couple of her friends (but I think they have fallen out of contact with each other too). Should I send her an email? I dont want to be all creeper-ish on facebook and get my *** handed to me either 
Many Thanks if your able to help my predicament
