Guys! Would you mind if a girl from uni who you know only by sight add you on facebook?

I’m really really into that guy but I am lack of confidence and braveness to add him. I know his name beacause I find him in the uni’s system. He’s 34, I am 23.

So officially I don’t know his name but in practice I looked for his name. We see each other every week, last year once he told me something and few weeks ago when we walked past we looked at each other for seconds. I don’t know his relationship status. Would you add him on facebook in this case?
