Alright reddit, I need your help. I'm an 18 year old guy (freshman in college). I graduated high school last year and I had a huge crush on a girl but for whatever reason I didn't act on it. 

I'm in college right now but the only girl I have interest in going after is the one from my high school. I know it's only a crush but we have a lot of things in common and i don't want to just forget about it. I only live about 40 minutes away from my hometown so it's not like I'm across the country, I am home probably every other weekend. 

I was in a class with her last year and I would say hi to her and smile but really nothing more than that. I'm friends with her on Facebook but I don't have her number, and I think I could get it from a mutual friend but I don't know where to go from there. And I think just talking to her on Facebook one day would come across as creepy.. Is there any way to talk to her without being creepy seems how we have never had a full conversation? This situation is really aggravating me, the girls i've dated in the past were girls I saw everyday in school so I could talk to them and not be creepy.. What do I do?
<bot>: have a crush on a girl from my old high school (she's a senior), might be able to get number (not positive), friends on facebook. How do i initiate conversation/ get a date without scaring her off?
