Fortunately I remembered her name though and randomly searched it on facebook's website and saw someone with her name that looked just like her. Out of curiosity to see if it was her I added her and later found out it was her. She first replied back from the add with a private msg over the site saying "How the hell did you find me?". Then I replied and explained to her what happened the night before as if she wasn't the same girl under the impression at this point from her reply that I probably added the wrong person.

Then she replies back that she is the same girl.... now I don't know what to respond with or say back I feel like a stalker-ish type of creep just due to the fact I actually found her like that without even knowing what school she went to or her last name. Any advice as to what I should reply to her with or say or do here would be greatly appreciated I am at a stalemate type of situation here where I am about to just not reply and give up :(
