Most Helpful Girl
I'd say if he does a lot in the community, then join him in these activities.
In this way, you'd also get to know him better.
Don't wait for him to make the first move, because it doesn't seems to be happening anytime soon. Just ask him, tell him you are free on this day, you have nothing on, and if he wants to hang out or anything. Ask him what does he like to do in his free time, and if you're down with it, just join him.
The worst thing is regretting not doing anything about it.
