He's just playing games. They will do that, arabs especially. They're very smart, and like to push your buttons, I think. He might be bored, and want to play with you. We had an arab like that, he started up playing hard to get, and I'm not big on running them down. I just don't like it - if it works for you, good for you, but it's not my thing. What did work for me, was that I went out like I was going somewhere else entirely and ignored him. He couldn't stand it after a few minutes, and had to come see what the hell I was doing.
