Why not agree to meet him for coffee or just a drink. It's not like you haven't met him (or could he be making that up? - can u check?) I believe it could be good. And that you should give him a chance. Give him the benefit of the doubt unless he does something that is a deal breaker. Be up front about it being "just a drink". I say - go for it - what do you have to lose. But as always - be safe & let a friend know where you are going.
