Should I add him as a friend on fb?

[Ling Lao]

I've had a crush on this main guy for almost a year. The issue is that we're both shy and everytime I'd stare, he'd always do something to get my attention. I finally decided to speak to him and he was just utterly nervous. We have continued staring at each other. I have googled the signs of a shy guy liking you and he does almost everything. Last week we were in the cafe and he sat on my pc. We spoke then he stood quiet for a minute and said that he had to go. He said that it was nice talking to me and that I'm very intelligent. The following week I saw him again and greeted him. He said hello to me and stumbled and shook a lot. Then after I asked him how he was doing, he walked away. He then came to the cafe near the area we spoke last week and walked really fast. I just found his facebook and I'm scared to add him on fb. What should I do? I want to add him but I don't want to creep him out what do I do?
