Why are we friends again?

Ma and him talked today, apparently he thought we hit it off (again) and we walked home together. I know he will ruin my life, i know its going to be all my fault for letting him in again. I cant belive im so fucking retarded! I know he is going to break me down, but i will always just come right back. Like a scab over a deep cut. The way he looks at me makes me think he wants Everything back to what it was but part of me knows he gives everybody thoes eyes. He bought be a candy bar today though! I guess thats somthing...
