That is terribly creepy... Seriously, his behavior seems very stalker-ish
(that or I'm watching too much crime drama). Either way, his behavior is very inappropriate, and in such a case, I see no wrong in going into bitch mode and laying down the line that he is very unappealing to you and you're not remotely interested in him. I'd hate to see it get to the point that you'd need a restraining order.
