Only the Past

How do I do this
On my own
What once was our haven
Is not even a home

I take my blame
Though not all was me
But if that's what you say
I'll just let it be

I don't know what happened
Or maybe I do
What once was love
Is no longer true

Time has not been kind
I felt alone too long
Living in the same house
Happiness is gone

When you start that walk
Don't ever look back
There will be nothing for you
I will only live in your past
