Fatal Flaw

I've come to the realization that I have a problem loving. With my over analytical attitude, I spend too much time processing every factor of a situation. I spent too much time being withdrawn and let the images of tarnished relationships scar my inner being. And as a defense mechanism, I've developed this uneasiness of the newly acquainted. Knowing all the bad that can come from relationships with people, I refuse to openly trust the newly acquainted. Even if there's a mutual attraction, I can never jump in with both feet before the deep analysis takes place. Fear of the worst develops a lack of trust. The lack of trust opens the fear of loving.
I'm at a place right now where I confess that I am not looking for a significant other, but I enjoy the company and attention that comes with having such. I want love, but I refuse to give it openly. It is now that I realize how cold life has truly made me. I'm not sure when I developed such a bad attitude toward being open or the idea of it. By far, it has to be at its all time worst.
