I'll Call You...

I've always been an avid gamer, from Monopoly to Scrabble to Battleship and everything in between. But I've never appreciated mind games or games that involved people's feelings.

Someone please explain this situation to me:

You met a nice guy and spend an entire evening talking and laughing. When the evening ends, you're ready to just go home and leave it at that. You've always been one to believe in fate. If you're meant to be with that person, your paths will cross again. Well, he's not that kind of guy. He compliments your thoroughly and asks for your number so you can go out again. You willingly give him your number and a quick kiss before you leave. Things are sounding good right?

Two weeks pass and he still hasn't called. You decide to take matters into your own hands and get his number from a friend. After all, this is the 21st century. Girls can be the one asking guys out. You call him and get his voicemail. You leave a nonchalant message and leave it at that. He calls you back the next day and leaves you a voicemail. The voicemail sounds nice and friendly, almost as if he's been waiting for you to call. You call him back that night, but it's the voicemail again. The weekend passes and he still hasn't called you back. So after the weekend, you try again. Once again, it's the voicemail. He calls you back the next day and leaves an apologetic voicemail. He's been busy and he's sorry that he didn't have a chance to call you back. He tells you to call him back. You call him back that night. It's been a week and he still hasn't called you back. You try again, but to no avail, it's the voicemail again. You wish him a Happy Thanksgiving and leave it at that. You still haven't heard from him.

Can someone explain this situation to me? Is this some kind of weird mind game that I'm just not aware of? Why would a guy pretend to be interested but never call you? If he was never interested, why did he ask for my phone number in the first place? And when I called him the first time, why did he bother calling back if he wasn't interested? Have I just been out of the dating game for so long that I don't understand the rules anymore?
