Nothing to do with you

This decision was mine
I'm ok, I feel fine
It's got nothing to do with you
Won't you leave me alone
I'd like some time on my own
It's got nothing to so with you

Now you look at me strange
Like I should be ashamed
Like I'm lying but thats not true
But this decision was mine
And I'm ok, I feel fine
It's got nothing to do with you

I think I'm letting you go
But theres one thing you should know
It's got nothing to do with you
I haven't found someone else
It's just that I'm not myself
And it's got nothing to do with you

But still you look at me strange
Like I should be ashamed
Like I'm lying but thats not true
But this decision was mine
I know in time you'll be fine
And it's got nothing to do with you
