Why?

I heard about you the other day
I heard you were well that's what they say
That you met someone else and that hes a really nice guy
That you are happy and in love, that you were flying high

And I start to feel sick
It makes me want to cry
And I pretend I don't care
Even though its just a lie
I know its been so long
So why do I even care
About a loss of love, that was never really there
