Feelings, what are those?

Relationships. The bane of my existence. To put it simply, I suck at them. I can find a guy that is the easy part, they like me that too is easy. However, I have this issue called running. When I guy likes me that is my first instinct that is why my greatest relationships are with guys that challenge me, that make me hate them. It is a strange way to live really. I tend to 'talk' to a guy for a long time before backing out when he admits anything to me. Needless to say, I found one that I really, really like. Too much actually. We had been talking everyday, all day for the past month. Then it stops. Out of the blue. And for once, I am at a loss. Kind of hurt and confused. This is why I hate relationships, that feeling is not right. I hate not understanding the situation I am in. I want to know everything about why it happened. I am so laid back that it is hard to believe that when something like this happens my mind kicks into overdrive and I want to know WHY?!?!
