Should I do it or not?!?

[Dahlia]

Hey guys. I was at a wedding last weekend and this guy caught my eye. We didn't talk or even introduced ourselves to each other. But noticeably through out the night, we'd always be at the same spots. He even stood behind me for the couples group photo.
Been thinking about this guy for a week and I luckily found his Facebook.

How should I approach this situation everyone? Should I add him? If so, what should I say regarding who I am? I'm 22 looking for a serious answer as lame as I sound right now.

If he didn't bother to get your number, he wasn't very interested in you.
He never even spoke to you-- doesn't that tell you anything?
