i want to use all the words in the world, they keep running through my head. but where are the ones that will make him see he's wrong?

he said he wasn't being fair to me to keep me around while he was unsure. how is this at all fair. how. it isn't. and i know i said i would do whatever he wanted me to.. but i didn't actually think this was going to happen. how could i. how could i. and if only i had said something different in those two seconds he decided to do it. i can't do this. i don't want to.
