Why couldn't I just tell him?

I found out today
That today was the last day
Please don't walk away
Please tell me you'll stay

Your leaving me here alone
When I haven't yet told you
The secret i've kept
I waited so long
..It was too long

I wanted to tell you.. that I..
No I can't now it's too awkward
You tell me somethings
That I know you mean only as a friend
In spite of it all
I let down my wall

I let you in
In high hopes you'll be
More to me than just a friend
You walked out of my life
Went out with a big bang

I sat in the corner
Let my head hang low
I had my chance and now it's gone
I should've said it
But I can't now...

I wanted to tell you that I...
I can't do this
I'll give you a hug
Tell you I'll miss you
And wish you the best of luck

Hating my life
Knowing my futures going to suck
Wanting you back
The self estem I lack

Years down the road
Been through a few marriages
Had some heart breaks
Met you on the sandy banks

Looked in your eyes and finally told you
I love you
please dont walk away..
Gives me a hug and says
Thought you'd never tell me
