What should i do?

So this guy has been coming to volunteer at my work's events several times this past year. The last time he came, I got a good look at him and thought he's kinda cute.😏 we got to talk a little more and I thought it's pretty interesting that a guy would like spending hours at an art museum. We didn't talk a whole lot because I was working at my event, but recently I added him on Facebook.

I'm not sure he's exactly my type but I kinda wanna get to know him more. Ladies what should I do? Should I message him to chat and get to know him more? Should I just message him to hang out in person? I don't wanna embarrass myself and I'm scared if we do hang out and I realize I don't like him then it'd be awkward to see him again at work events. Should I do nothing and wait to see him at the next work event? But it would probably be months from now and I would most likely be working and too stressed and busy to have a focused conversation with him.

What should I do? 😕
