Why Does Love Hurt So Much?

We can't always expect the path of Love to be smooth.This is how i felt after it hadn't.

I can't give you more than I have,
I can't love you more than I do.
Now you turn away when I need you the most,
But why do you do it ?
It's not that you don't love me,
It's not because of fear.

I give you all that I am,
I give you all of my soul.
So why turn away when I need you the most ?
Do you fear to show your love ?
Are you scared to say you care ?

I have given you all the love I have,
I have shared with you my fears,
So don't turn away when I need you the most.
I feel your heart so full of love for me,
I know you need my touch.
Maybe its the fear of it all,
Maybe thats why love hurts so much.
