Riddle

The colour people associate me with is red.
You might show me with a box of chocolate's.
I cab grow big
and i can grow small.
I can be pure
I can be true.
People show me with flower's and hug's and kisses.


I can make you feel wanted or all alone.
I can tear you apart or make you cry.
I am the complete opposite of hate.
What am i??

LOVE!
