"Don't want to call you in the night time, don't want to give you all my pieces. Don't want to hand you all my troubles, don't want to give you all my demons. You'll have to watch me struggle from several rooms away..." it's him pushing people away. He doesn't want people to know everything about him, because in the past, he gave them all his pieces, and that person left, so now he keeps it all inside out of fear someone will do it again.
"But tonight, I need you to stay." This time, he needs them to stay. He needs them to stay because he has a particularly bad feeling about what he might do, or will do, if they leave.
"I've killed a man and all I know is I am on the run and go" I have killed a man could be two things, but they are both him. He either committed suicide, or he killed the person he used to be, or could have been.
