I didn't know

I hadn't seen you since you ran away
You'd been in the shadows
But I saw you today
I washed you off me like water to soap
But I didn't know that I still had hope
Yes I didn't know till I saw you hand
Holding the jacket of another man
That's when the heartache struck me
Like a knife in the dark
Through the secret place in my heart
Where my future life would start
But I didn't know
No I didn't know
That it would hurt so much
To finally see you go
Into the night I crept back again
An animal wounded hiding in pain
I didn't know, I didn't believe
That I'd feel so lonely
Watching you leave
That's when the heartache struck me
Like a knife in the dark
Through the secret place in my heart
Where my future life would start
But I didn't know
No I didn't know
That it would hurt so much
To finally see you go
