Thick and thin

Sometimes i wonder if the reason you left was that it was something that i did so i relive all of conversations in my head and i come to the conclusion that is wasn't me that it was you that you go scared and left me by myself to think why would he do this to me of all people the person that was there for him through thick and thin.....then after I'm done hating you and i come to my senses i realize that your the one i want to be with the only one and that's all that matters to me and i want to spend the rest of my life trying to convince you of that and try to make our relationship better
