Oh my god.. what if he doesnt like me?

Ive been speaking to this guy online for like 2 years.. there was a point where he was saying he loved me and we flirted loads. I used to really like him. Anyway we havent talked for ages now maybe because by coincidence we have found out that we are going to the same college... I will more than likely see him EVERY DAY because his course is on the same corridor and I hadnt even intended to meet him.. Im like real shy in real life.. so what if I cant even talk to him?? And we will both be so embarresed because like we used to flirt and have big chats and stuff.. but now I wish I could take back what I said because I wish I hadnt said those things before Id met the guy! And now I am and Ill feel so silly! What would you do?
