What You Can't Have

History of relationships show that for some reason people want what they cant have. What is is about a person that shows no interest in you? The little bit of attaction they show you, you hold on it tight for dear life in hopes that the image in your head of yall being together will come true, one day. But in this one situation I'm not on that end. The situation is actually more twisted. This guy wants me so bad but I'm not sure how bad i want him. He offers his all to me, tells me he'll give me the world but i still dont have a desire to be with him anytime soon. I'm not sure if thats bad on my part or not. But all i know is, its very frustrating! I mean seriously he's a good guy and all, very nice but he lost that "thrill" that essence of me wanting something i cant get is so far gone. When a good man or women wants you, and is willing to give his/her all to you, and when your not ready to give your all to him/her. You dont want him/her. But you waste your time chasing the person that you know you cant get. The person that gives you that little bit of hope and security that you miss out on a good thing. So what to do???
