It's in the Back of My Mind

I don’t know what I’m thinking
I don’t know why I’m taking you back
After all the heartache
I ought to have my head looked at
Tell me why you cheated
Don’t try to pass the blame on me
I gave you all you needed
And still you have to play the field
Oh yes I forgive you
But I wont to forget
I want to believe you
But no matter how hard I try
It’s in the back of my mind
All the time
It’s in the way that you look my love
And Threw it aside
Always in the back of my mind
Can you give me one good reason
Why I should be taking you back
After all this heartache
Oh I gotta get my head looked at
Always in the back of my mind
All the time
