Is it safe to send him a friend request?

There’s this guy who’s been showing signs of interest when I see him a few times a month at social events. I noticed last night that he seemed to have backed off considerably. He didn’t speak to me and didn’t seem to be in a good mood. I overheard that he wasn’t feeling well (had a cold or flu). He left early. Is it ok to try adding him to Facebook, yet? Or should I give it more time?
