I have a huge crush on a guy who I met irl over a year ago. We have several mutual friends, including my older brother. I'm not comfortable letting any of our mutual friends (esp. my bro!) know of my feelings so cannot enlist them to help me with this. I would of course prefer talking to him face to face, but I don't see him that often and whenever i do, he's always surrounded by a bunch of other people. And I'm fairly shy.
I have no idea if he's interested in me or not. The last time i saw him in a pub I was walking past him (hadn't realised he was there) and felt like someone was staring at me. I looked at his direction and he was just turning his head away from me, then he probably realised I had noticed him and turned back again and this time looked at me in the eyes for what felt like an eternity (that's a sign of interest, right? Or he could've been stoned, who knows..
) I smiled at him and said hi, he said hi back, but didn't really smile. He didn't look unfriendly or anything, but surely you would flash a smile to someone you're interested in?
Anyway, I finally got the courage to send him a friend request on FB on friday night and he accepted it immediately. Can't get too excited about that though, because he's got a 4-figure number of friends in there, so he probably accepts all the friend requests he gets without a second thought. I spent the weekend going through his page, he's definitely single, definitely straight and between the lines I got the impression he wouldn't mind meeting someone.
But i just don't know how to start a casual conversation online with someone I barely know? Also I think I'd be mortified if he didn't reply at all 
I know I'm overthinking this but I can't help myself
