Lyrics of I'm not so easy anymore

I'm not so easy anymore you'll find it rougher than before
I guess you've noticed how i've changed since you've walked out the door
You say you made a big mistake but you're telling me too late
You just can't come back like before i'm not so easy anymore
I know just how you work and i know that you'd hurt me again and again
Your being here is no surprice and i can see it in your eyes
You need a friend it won't be me
I think it's time that you should go back to the friends you say you know
And tell them i've been keeping score i'm not so easy anymore
I think it's time that you should go...
