Looking back

they say: never look back.
but what if it's all you need?
'cause back then you were here.
and now you're gone.
I know what you did must be wrong.
I won't forgive you and I won't forget,
but the good times we had, I thank you for that.
I wonder if it's ever too late to talk it over.
I wonder if a heart can heal.
I wanna see you one last time, to really tell you how I feel.
