Love is pain not happiness

We say love is happiness
A form of joy and bliss
But is it really that way
When someone tells you they will stay
With you forever
And then they leave to come back, never
Love is a form of pain
Sometimes it works out well in the end
But until you find the right person, it's tears you cry
You search as days pass on by
Your heart aches, your stomach spins
Love causes pain and sin
When you live for love as I
Love is your slow form of suicide
