Can someone tell whether my ex was a vampire or not? (Do vampires exist?)?

Well, I know it sounds A LOT like a vampire, but he most likely isn't. The teeth part might be a lie to impress you and other females, and he's probably a big vampire fan, and is trying to convince himself he is one. His finding girls very attractive doesn't really have anything to do with him being a vampire. And anyways, as far as scientists know, mythological creatures like Nekos, vampires, werewolves, witches etc. etc. do not exist, even though sometimes I wish they do ^_^
