Alright so I met this chick in one of my classes during freshman year (September 2010), it was public speaking and the teacher made everyone pair up and get to know someone (it was a 5-10 minute back and forth conversation) then we had to give a speech about them...so this smokin hot chick chooses me for the assignment so we did the assignment and I never really talked to her again, I've seen her around campus a few times since then but nothing really came of it. I always sort of had a crush on her but at the time that we met I had a girlfriend and didn't want to mess that up but it eventually ended last summer (2011) but all of a sudden a few months ago I just started thinking about her more and more and I can't get her out of my mind...I have no clue what to do..I have her as a friend on facebook but I don't know how often she's on I never see her posting and I know first hand that trying to get something started on the internet doesn't work..at all...and I have no clue if she even remembers who I am or that we even met and I know there's a chance I'll creep her out big time and ruin any chance I COULD have by randomly messaging her on facebook and I'm at a loss of what to do so I ask anyone who's reading this...

Any advice on what I should do?

If this isn't the right forum to post on, let me know I literally joined this forum 5-10 minutes ago...really desperate for help

Thank you in advance
