Why does love hurt.?

Why does love hurt.?
It clutches at your soul,
It can bring you so much peace,
That your heart is on a roll.

Why does love hurt.?
When it's so, so far away.?
Desparately reaching out,
You know I'll never stray.

Why does love hurt.?
I think I might know why,
It caresess your fragile heart,
Maybe no need to ask 'oh why'
