He

I know that I hurt you
What I did was so wrong
I made a mistake
Those feelings don't belong

He was close to you
And then close to me
We got closer
Then any person could be

It was an accident
I didn't mean for it to happen
We've grown apart
Our friendship has lengthened

I didn't mean anything to him
I was just some rebound
He just wanted someone
To use as a playground

So I'm sorry I hurt you
I was his cover
I don't it doesnt help
Because he's your brother
