My dear baby... I love you

What had I not seen?
What had I not heard?
Your eyes searched for me
But your lips were pursed

How could I not know?
That you were slipping away
How did I not know?
That from within you frayed

Why didn't you let me in?
I could have helped
Why didn't you let me in?
I could make it end

When did it go wrong?
I don't have a clue
Was it the day that
I forgot to say 'I Love you'?

Have I watched you wither?
Right before my eye
I think it was your smile
That safely said the lie

I don't know what to do
With the world I build around you
So many questions
But the answers are gone with you

How will I know what went wrong?
How will I know what pushed you over the edge
Was it something I did or
Was is something I said

When did it go wrong
I haven't got a clue
Was it the day that
I forgot to say 'I Love you'.
