I may have gave someone the wrong number by accident? HELP

PeaBrain
Ok so I met this guy when I was out, I was pretty drunk when he asked me to put my number in his phone... I have a tendency to type the wrong number when I'm drunk completely accidentally, I've even done it to one of my best friends...

Anyway I don't know whether I did give him the wrong number or whether he just hasn't text me? I added him on Facebook and he accepted but I'm too scared to inbox him saying "Oh I think I gave you the wrong number" in case I hadn't and he just didn't text me? Ah what do I do?
