Feeling used?

My dad cried when he saw me. He hugged me tightly. I silently watch him cried, i pretend i didn't care, i don't want to show him that i miss him, but i know to myself that no matter how sh*tty father he was, i still loved him. I know that his tears are fake. I know his trying to use me but I've learned my mistake. I don't want to be used by him again.
