How to contact him...

There is this guy who I find attractive. I've seen him out and about quite a few times but haven't ever said anything or been introduced. I added him on FB bc we have friends in common and he has liked a ton of my pictures. How should I approach him? I live in a small town but don't know when I'll be out again to run into him. I don't do the bar scene that much! Do guys find if awkward if girls message them on fb?

Its not awkward at all, unless you make it awkward.

Just message him. That alone makes your intentions pretty clear, he will know what to do from there, or should..

You could do the classic bumping into him and apologizing then saying how you've seen him around and how he's doing.

Don't do that.

If FB message doesn't feel right, find a friend you two have in common and get introduced.
