What is love? Did i get it right

To love for the joy of loving is love in the real sense,
From want or need love never really does commence.
To love is to let go of all your defenses,
Accept being vulnerable and get rid of the pretenses.
You say love gets you writhing in pain
You beg for peace but all in vain
But as you sense the longing within you
You realise that ,after all
Love seeks to embrace your pain.
