High school crush is back...what should i do??? ?

So i liked this guy during my senior year in high school..he was one the most liked guys in school. had tons of friends..lets just say one of the popular guys. I was very popular too but for some weird reason we never talked or became friends, we had diff groups...so anywyas...I never liked him and in the middle of senior year i started to noticed that he would stare at me some times during one of our cles then would look away when i saw him..yet he didnt say anythig..neither did I. So time went by..we both graduated and so by the end of the year i had this huge crush on him because somehow with his few stares he got my attention and i couldnt resist but to like him. After graduation I never saw him again and i eventually got over him. Its been about a year and a half and he happens to attend the same college i go to..so now I see him every blue moon walkin across the campus getting out of cl or something..most of the time alone. surprisingly. And the crush i had for him is coming back because he looks even better than before lol. and even now I saw tha when he sees me he gets somehow nervous and stares at then look away when he sees me. YET he doesnt say anything. what a chicken! gosh lol...So anyways..EVEN MORE FUNNY. He happens to work at the same place i just got hired at..and i dindt even know he worked there. haha Im tellin yu is like the worlds wants us to be together and always puts us together over and over again. everytime im like ok im over him..he randomly appears again...supergay...THEREFORE. my question IS...what should I do about this? obviously teh guy is too much of a chicken to talk to me so I guess igotta make a move. But im also a chicken and very scared to be rejected, i hate that feeling.I know ill see him A LOT more now since we work together and eventually will become co-worker buddies. I think it will be very awkward at first but then will get better..So again..what should I do or say to kinda see what he wants..at this point i dont even know if he's boyfriend material..i know nothing about his personality...all i know is that his very sociable, likes to paty and dresses fresh..and that ha havent had a gf since HS. ayeb what it is is just a call. I like him so much that maybe its just ual attrction that i have now..so BACK to my question, what hsould I do once we start talking? I don' wanna seem like a freakin stalker or anything but yu know...just be cool and see what happens...
