How could this be true?

Is this is it
I ask myself
Giving you up
To someone else

You loved me first
And i you
You held me first
But how could this be true

I see you love me
In your eyes
But mine act to you
Like a disguise

I'm sorry for
What i've done
Breaking your heart
Uprising like the sun

Please forgive me
I still love you
My eyes like a river
How could this be true

Do you really love her
You say you do
But i know you love me
It is true

I was so mean
I admit it too
But Ii'll love you forever
We both know its true
