The most pain ive ever felt. And it just wont go away

Its hard to understand
Its hard to explain
Why love can be so heavenly
Then crash and cause so much pain

Love can beautiful
It certainly was to me
I took it for granted
You were right to leave

I don't understand
How you can affect me so sadly
Im pathetic for crying..
But I miss you so badly

My cries fall on deaf ears
You are now moving on
But how can I do the same
When Im held back by 'our song'

I'm crying myself to sleep
I'm avoiding the radio and you
But atleast I once knew..
How love felt, when it was 'true'

Baby, I miss you
I mistreated you somehow?
I didn't know what you meant to me..
but atleast I know it now..

It's too late for me
i'll never move on
the next girl to have you
is the 'luckiest' girl known.

baby im sorry,
i really and truely am
Pity it's to late now
But you will always be.. My one and only man
